Why can't the smaller places be closed and moved to the airfields? - and don't quote tradition. The RAF (traditionally) only had bad habits.

There is no reason anyone really needs to be "based" in London, or anywhere in particular, anymore. Move 'em out!
Make 'em live "Life in a Blue Suit" properly!
