Whilst I can theoretically see the attraction of a Tory win in the next GE boosting SNP support, in reality it would a complete and utter disaster, not just for Scotland, but the entire UK. At the moment the Tories know they're fucked, so they're ripping the absolute arse out of it in terms of corruption, horrendous right wing policies and general cuntery. If they somehow win another five years, they'll think they're untouchable and we'll have further erosion of voting rights and brutal welfare reform to look forward to, in fact we'll probably be well on the way to a fully authoritarian right wing government which will be nigh on impossible to remove. Devolved parliaments will probably be completely neutered as well. There is nothing more dangerous in politics than an emboldened Conservative government.
As much as i despise what Labour have become over the last 15-20 years, Starmer's diet Tory pish will be still be preferable to the full-fat version.
