This idea's been bouncing around in my head for a while, so I'll give it a shot-what if you bought a Conn 20K, took it to a repairman, and had them add a thumb-operated 4th valve that would approximate the 1-3 combo? It seems as though this would impprove the playing, although it would add some weight and a weird protrusion of tubing from the horn. Feasibility?
