I would swap out one of Bath, Bristol or Southampton for somewhere with an AAA/AAB offer, maybe even Imperial because it doesn't actually offer a higher quality aero course, the only potential advantages it has are its F1 links and living in London. They each offer quite different courses and locations so it shouldn't be too difficult to do.
Personally I would drop Southampton out of those because the course quality isn't great from what I've seen and they really over-advertise what they do have. It's also in a small city which is a thing that a lot of people end up hating, and while Bath is in a similar situation they have a free bus to Bristol so you have easy access to all the things that a larger city brings.
