I might need to use a service or rented GPU server instead of local if my 3060 can't handle it, but I also know that beyond a certain size, non-AI upscaling with tiny touch-ups would be viable.
I can also go the big balls way and, despite my lacking artistic skills, take the once-upscaled image, blow it up, and trace it in vectors and pray Inkscape (no, I WILL NEVER use Adobe, not even pirated) doesn't ruin everything. Would also allow for some other minor fixes.
Either way, right now I'm focused on finding designs and poses for the A and B sides that I am happy with and come close enough, and then I can start the work on refining those.
One step at a time.
