That being said, what exactly are you trying to do? It's already possibly to PROCESS a file from another TT file. Is there something specific you need to do that PROCESS does not do?
If you simply need to modify existing stash variables, or add new stash variables, you could probably get away with a TT wrapper file that manipulates variables and then calls PROCESS on another tt file supplied as an argument.
