The CAAD12 fork will clear a 32 GKSK with a Sram Rival caliper but the rear brake bridge is usually the issue on any bikes designed to use short drop calipers.
There was someone a while back talking about putting an RD hanger on a Steamroller and i remember thinking why the fuck would anyone do that...

A mate of mine has put 1x10 microshift on his steamroller. Spaced the rear dropouts, put a hanger on etc.
Honestly I dont think it rides great but he likes it.
If I were to do any mods like that, it would be on a Kona Paddy Wagon, they are a more relaxed road geo than the steamroller and can easily take 35c.

But don’t do it. I did on my SJS and it was awful.
Probably not quite 32c clearance but some of the latest rim brake models like CAAD13 or giant TCR would have a bit more clearance than your bike
