The first person I would call is Max at Traxxion Dynamics. They fabricate a triple tree for the B and his business is suspension. With his recent videos on the new Wing and his new shocks for it, he obviously doesn't waste any time designing and manufacturing products asap. I would bet that if he thought it was feasible, he'd knock out a custom tree for you about as fast as you can spit....at a custom price though. Then, if he thought it would work, you might be the beta tester for the new tree and might could work at "deal" testing it out. He's got everything at his business to CNC that new tree for you. I'm curious if he's already considered it at some previous point.
