If this is something you're interested in, why not pop onto the mailing list
and join the discussion? Take a look at the patches being proposed and give
feedback. It sounds like you have understanding of TTM which people in that
community might not have. Go help them out.

Also, I've briefly described my thoughts of what they could do, but you're
getting 3rd-hand information from someone who's no idea how TTM or even GEM
works and has no idea what the community's goals are. I'm probably wrong
(very likely in fact), go find out for yourself! :-)
