Would it be stupid to set up a C3 with a 1x12 drivetrain so I can throw a really small chainring on there for the big day? Yes. But getting a 105 bike and swapping the crankset so I can run a smaller 1x chainring seems a bit less egregious. I think that's what I'll do. Then if I can do the climb, I'll reward myself with sessy wheels and groupset. If I can't do the climb, I'll burn the bike.
