The single piston D52s are available in a range of sizes from 2 3/8” to 2 15/16” factory and I think down to 2” aftermarket.
Just a FYI thing I haven’t seen mentioned.
Ive always had 1 1/8” master cylinder with power when using the big calipers.
Using a 1 1/8” Corvette disc/disc mc with power and big D52s on the CR.
