This following question is purely hypothetical. I read and hear about people complaining that the 450s are not suitable for the Portsmouth to Waterloo via Guildford route or that they don't like the seating in them and so on. Would it be possible to build a train that can carry the numbers travelling on the Portsmouth Direct route that these commuters would like? I'm not asking for it to happen. Just wondered if it would technically be possible. I suspect not, given the numbers travelling but someone more knowledgeable will have a better idea either way.
