Low profile or quick release track feet

I'm trying to figure out a track mounted system for my ARE MX and running into a height issue. Does anyone know any ultra low profile feet that are track mountable?

Otherwise I was thinking on getting some sort of quick release feet where the base would stay mounted in the track and I'd have to pop on the crossbars/platform when needed. I know Rhino and Frontrunner have options but it seems tedious.

 

My yakima rack that's mounted to my shell tracks comes off in less than a minutes. The landing pads stay on the tracks, and the towers/crossbars come off.
