Were Britain's plans all along to exile Napoleon to someplace like Elba? Let's say someone gets lucky after one of his battles, Austerlitz, Eylau or Wagram or whatever, but before the Russia campaign, and captures him. Woudl he capitulate and just come back like he did OTL? If so, would he be able to wreak more havic since he has more at his disposal?
Or, before the Russia campaign, could the European powers sue for peace, let him have France (and maybe some of Italy) and just leave Britain hanging? After all, he was offered a peace in 1813 IIRC, but not by the British if I understand. (And, without many troops ont he continent, maybe the British couldn't do anything before 1813 or so. Which would be bad news for Spain if it's after his invasion there, as he might try to keep it in negotiations.)
