Here's a Guardian survey for you Maddy. What they say and what they would accept, may be entirely different.
If they do get independence, the UK public certainly want to poo poo the SNP despite their denials that nothing would change.

The recent British Social Attitudes survey, published in June, found that, although people in Scotland say they are opposed to nuclear weapons (46% against, 36% in favour), when asked for their views on the following statement:

If Scotland becomes independent, Britain’s nuclear weapons submarines should continue to be based here

41% agreed and 37% disagreed. Strikingly, only 26% of those in England and Wales thought Trident should stay in Scotland post-independence; 63% said the submarines should “definitely” or “probably” be moved.
