What an awesome power set! Looks like a blast. Seven has her three powers and is extremely happy with them. Unless she has a really good reason not to be she's friendly with everyone, so I don't see why she wouldn't get along with GT. She just hopes GT doesn't burn out and end up a stump like the Silverstein GT. Jussayin.
Charon, however, only has two. And I'd be completely up for him getting a third from her, if you're ever interested.
