Apart from further separating out suburban services, I wonder if it is worth considering whether there are any routes that would be better off transferred from TPE to Northern or vice versa? E.g. the fast Leeds-Manchester via Bradford could fit better under Transpennine, and there is arguably little justification for intercity-standard trains to be serving Redcar.
Under GBR I'd have 2tph Liverpool-Newcastle fast as true InterCity services using long trains (e.g. 9 or 10 car 80x) and with full on-board service - basically the same as LNER. Similarly the WCML services would change to using as long trains as possible that can be accommodated at Manchester Airport (807s would probably be perfect) and move to the InterCity West Coast operation.
The rest would just go to Northern/Regional Railways/whatever it ends up being called as regional expresses, along with the 185s to operate them, being broadly similar to the Barrow/Windermere and the likes in concept - particularly south TPE. Though that said I could see a case for a fast Liverpool-Nottingham once an hour using 5-car 80x as a true InterCity service.
