Well, this leaves one more option. Upon Scottish independence the United Kingdom gets disolved and the Kingdom of Northern Island becomes a separate member of the Commonwealth. Would that be possible? Again, conditional on Scottish independence actually prospering.
No. Nobody is going to touch NI constitutional issues for a long time.. and with good reason.
Well, that might not be up to even the (Northern) Irish - or, for that matter, the English. If Scotland gets independence, the constitutional issues in the rest of the UK would have to be touched, wouldn't they? Even the decision to stay in the UK will not be exactly the decision to maintain status quo - it would be a very different UK.
The UK will be maintained regardless - it will just be the United Kingdom of England, Wales and Northern Ireland. 
On paper, yes. You'll get obvious obvious suspects screaming "If
they can be independent, why the hell can't we?" (Which, if you look at Scots Independence from that standpoint, it makes the whole idea appear the bit more silly than it already is.) Don't know if anything'd come of it though.
