One of the main strengths of the ECML, compared with the WCML North of Crewe, is the level of traffic from Edinburgh (and beyond ) to the intermediate stations such as York, Doncaster and Peterborough. Nearly 60 years ago I used to catch the 08.00 from KX (you were almost certain to get a Deltic on an early service! ). It was almost empty on departure but we'll loaded before Edinburgh.
That kind of makes sense given that there's nowhere of that substantial size between Carlisle and Lancaster, whereas Newcastle, York, Doncaster etc are all fairly big. Yes, there's the Lakes, but there are also bigger and better and less touristy mountains in Scotland.
There's a reasonable demand from Scotland <-> Preston (and onward to Blackpool).
Lancaster would mostly be students, but Scots mostly go to Scottish universities as it's free. It's a nice enough place, but being in some ways a mini Edinburgh (hilly, stone buildings and a castle) I doubt it has much of a tourist market from further north - they'd just go to actual Edinburgh.
