Have you considered the international baccalaureate? I'm on it - you'd be able to take english, maths and history, possibly RE if your school provides it, or as an A level along side, but then you'd also take a science, a foreign language and either an art or another subject from humanities, science or language (i'm guessing you'd go for humanities?)
I've been on it since september (HL English, Psyche and Anthropology, SL Maths, Spanish and Bio) and I really like it, and it's only really now that I realise what I good choice it was cos i haven't limited myself at all =] [!]
It all depends on what you want to do in the future, if you think you are academic enough. etc. etc.
Basically, you shd do wot you enjoy, or else you'll end up hating it and being worse off =]
quote or pm me for me q&a / chat!
Gd Luck!
