I actually designed a set and was ready to start machining when I stumbled across these . . . http://www.timmonsbillet.com/CarbThrottleSpacers.html

I may still make a few sets as mine go from a Nicson intake with a slightly smaller port opening to a Zenith Carburetor - the inside of the adapter is tapered to allow a smooth transition from the carb to the intake.

It is still important to insulate them if you can - keeps the gas from boiling off / overflowing into the intake on a hot shut down.
