Now this would definitely completely overkill, but I'm curious and have to ask anyway: Is it at all in the realm of possibility to backport SLI support for Pascal/Maxwell GPU's?

Pascal was the last Nvidia GPU chip to support SLI in hardware, so possibly, though I doubt it would be a worthwhile thing, unless it could be implemented and significantly improved for XP.
