anyone in the Denver area that has done this mod to a -6A tip up that I could check out?
No one is even moving in Denver today. Certainly not in an airplane.
I claim to be the first to do it to a tip up 6a several years ago. My plane is in Longmont. Call me and come look. 303772twotwozerotwo. Best thing ever to happen to the airplane. The easy exit is good too but only useful for a few seconds per flight while the seat back is all the time.
