Mmm, I'm not sure if it's a good idea to name the band as the style that you play. There's some examples (Metallica comes to my mind...), but I've seen more often bands that use the name of an album or a song as a tribute (Scott 4, Starsailor or Spanish bands like Karma Police or El diablo en el ojo).
Possible "brit-pop" names: Morning Glory, Wonderwall, Supersonic, Parklife, Song 2, Beetlebum, Different Class, Common People, Drugs Don't Work, Creep, The Bends, ... Mmm, maybe "Common People" isn't that bad. And nobody will know that is a tribute name if you don't explain it. But maybe there's a band with that name already.
Good luck with your band anyway.
