This is (relatively) easy to do, since it involves applying existing 
btree GiST code to all the types you want composite indexes with. 
Basically no rocket science, just lots and lots of code (bindings for 
every desired type... there are a lot of types).

You could test it out by using the types that have already been bound in 
contrib/btree and seeing if the results are what you want.
