It's been done. I think all you need are the Caliber 30 motor mounts to get the motor bolt pattern correct, a Caliber 30 tail boom, and belt.

Most likely you could leave the boom alone and fly as is. But you may end up tail heavy. The 37 is lighter than the Hyper 5.

The stock gear ratio of the Caliber 5 is identical to that of the Caliber 30, so you should have no trouble turning the blades.

Sixth post down -- this was an OS 32, but the 37 is a drop-in replacement for the 32, you should be good to go.
