Cross country is in need of some investment, the voyagers aren't bad trains but (under normal circumstances) don't have enough capacity to meet the demand.
I think an ideal (if somewhat unlikely) solution would be to electrify between coventry and didcot (tying in with the GWR services to Oxford being run fully electric), and reading West and basingstoke. A new fleet of dual voltage trains (perhaps a version of the 80x, something similar to SE's javelin or something new). This would increase capacity on Manchester - South Coast services with larger trains (9 car sets or two 5 car sets joined), whilst freeing up voyagers to increase capacity on other routes by doubling up to create 8/9 carriage trains (such as are being run at the moment)
I know this is all wishful thinking, and unlikely to happen, but I don't think it's completely impossible (at least I hope not!)
P.S apologies if this has been suggested before
