At the moment all stations trains on this route seems to be two per hour, Northern to Manchester Oxford Road and to Warrington. So two extra paths per hour would need to be found, and platformed at Lime Street main shed.
When Lime Street got the last major rebuild, the approach tracks (and the need to cross over them) were said to be the big constraint on capacity. I believe Platform 1 is essentially served by a long siding as a result, trains arrive and depart on the same (5th) track to avoid crossing anything else, but this is on the North side so doesn't help.
The loss of the Edge Hill flyover produces a lot of conflicts where the lines split in the flat junction, and so some sort of grade separation is probably going to be needed - as it would be for Wapping tunnel. Maybe a junction scheme first with provision to use it for the tunnel as a second phase?
