Ive heard of butchering crv hubs onto ek suspension parts, im sure somewhere on hondatech.com some americans have done it.
Why not try a mgzs180 caliper/zr160 and a set of aftermarket pads with oem mgzs disc. Also remember that a 1inch master cylinder from a dc2/ek9 will help alot. It should provide braking very close if not identical to running a set of ek9/dc2 calipers as the pad/piston size is very close in size.
