@lemur I've given it some thought and I might take a swing at making an alternative daughterboard for the GT to accept the new Superflux V2 connector. Gonna be very DIY and hands on but a nice clean solution if I can pull it off.
Gotta finish a few other things up first. The new XR based controller housing for Fungineers is nearing completion so I should have some time after that to give it a swing.
