Well maybe inflatable rails? Something that allows a normal construction 85L board to go to to 100 by adding volume to the rails using a pump?
Or forget air and develop exchangeable rigid rails. One can envision a set of "bolt on" rails: two bolts for side, almost as quick installation as a fin. One board + two sets of rails (adding 15/20L) can make your board go from high-wind (say 80L) to mid (95/100) to low-wind (110/115L) in a blink.
