With a branch terminus at Botanic Gardens and presumably an exchange station with the Underground at Kelvinbridge? Also a bit of bi-di needed at Exhibition Centre (only platform 1 available).
The corridor between the Botanics and Exhibition Centre is entirely underground which adds a huge amount of money to the bill.
I'm going to give the vague but entirely accurate answer of "too much".
The number of people using this corridor really wouldn't be enough to justify the cost. Both of the proposed stations (Kelvingbridge and Botanic Gardens) are already well served by the Subway and bus networks.
Without necessarily disagreeing with the rest of your post, why would the existing tunnels increase the cost so drastically? Been a while since I walked them, but they are not in too bad nick as far as I am aware. The old Kelvinbridge station site is not underground, but it is perilously close to the water level in the river Kelvin.
Tram yes, heavy rail no. The Strathclyde Tram proposal in the early 90s involved re-opening this route, although it was only the Great Western Road tunnel that was to be re-used. If I'm not mistaken, Glasgow City Council still protects the tram alignment from other development as it is incredibly likely that it will eventually be built.
What route would a tram take into the city centre after it emerges from the Great Western Rd tunnel?
It would provide a fast connection from the south side to the west end via Central. The bus takes an age and St Enoch isn't really convenient enough for interchange with Central especially in poor weather.

Route for Line One
Kelvin Way, then Sauchiehall/Berkeley Streets, then Bath/St Vincent Streets (with east/westbound tram lines on the different streets).
Thanks for posting that. I suppose the proposed route to the city centre was the right one at the time (though I do wonder if a tram could get up the hill on St Vincent St between Elmbank St and Holland St). However, given the new employment sites which have developed since the Strathclyde Tram plan was drawn up I think if trams were being considered now there would be a case for routing them down Finnieston St to the SECC complex then along Lancefield Quay and Broomielaw to serve the new developments there and help regenerate the remaining gap sites along the riverfront.
I'm still not sure whether it would have a better business case than reopening the heavy rail line though.
That's something I've thought as well. There's an obvious tram alignment along the north bank of the Clyde all the way from Central Station to the Golden Jubilee hospital. The route via the Botanics is the other obvious one, but directing it via the Broomielaw would then miss out on most of the middle of the city centre. I think there might well be value in doing both but it's probably too much of an ask to get both city centre routes built simultaneously. Given that a Broomielaw tram alignment would be shared with a tram replacing the Fastlink route, there's probably long-term value in there being a connection around Finneston between the Botanics/Broomielaw lines and this could be used to funnel all three western routes into the one cross-city alignment.

It quite definitely would. A heavy rail reopening would cost a comparable amount of money and then require considerable ongoing subsidy, especially since it would be hard for it to properly serve built-up areas. Trams cost less to run in the first place and then can serve many more people and generate more revenue. For instance, instead of terminating at Maryhill shopping centre the tram could rise up and join Maryhill road. Then it would be able to serve all the people living along that route, interchange with the Anniesland line and also connect the Science Park to the rest of the university district in the west end. I'm also sure that the folk in Bearsden would quite like to have a tram taking them to all the fancy places in the west end too.

I also noted that the Strathclyde Tram would have interchanged at Queen St but not at Central. I don't see any reason why a single cross-city alignment along the riverside couldn't serve both Central and Queen St, boosting the business case further.
What do you about slow on street sections though? The tram would be quite slow through Finnieston for example. Would it be possible to create a new access to the disused tunnel at the south end of Kelvingrove Park and an exit somewhere before it reaches Exhibition Centre station? You'd still have stops on Kelvin Way as per the Strathclyde plan and another near the SECC, but you'd bypass the snarl ups in Finnieston. Feasible?
It could, but then it would be slower through the city centre and make it less attractive as a city transport system. We want people to go from the west to the east end and vice-versa, not just to the city centre. For city transport needs it's not as vital that it interchanges with both Central and Queen Street anyway, as it would be used more by people going about their everyday lives within the city.

What about operating a branch on the Glasgow subway along that line?
There once was a terminal railway station in Dawsholm (Caledonian Railway?)that closed around 1908, that was part of the same area of the line of the Glasgow Central Railway being discussed, which still had a locomotive shed until the 1960s.
Would that area as it is now benefit from a reopened station?
It already has one: Kelvindale.
