I think full indy is sadly broken now. I don't think it necessarily works at all after all of this. My opinion now is that the UK has probably seriously damaged itself, and actually, damaged the rest of Europe too. We've all been looking inwards a lot, there hasn't been much discussion of the effect that Brexit will have on the EU with one of the major pillars removed.

However you are totally right about the power imbalance as you shift southwards. My best case scenario, assuming Brexit does indeed follow through, is a "devo-max" solution for Scotland as part of the UK. Keep the union intact but fully devolve domestic decisions to Edinburgh.

I'd go even further and say that this might be the best solution for England, too: to be divided into three or four regions with similar devolved powers. London still "steering the ship" so to speak on the world stage (if we're even still relevant in 10 years time...) and devolved regional governments governing for the interests of the people of that region.
