Looking at the current unit, it seems the trigger shifter part is clam-shelled around what looks like a standard brake lever. If that is so, then removing it should be easy and, thus, not require purchase of a new brake lever. If so, then I'll only need the thumb shifter.
After my morning ride, tomorrow, I'll take a screw driver and test my theory....
Edit: a little search fu indicates that separation is possible but might involve destruction of the shifter part of the unit. I think smart money would be on acquiring the friction shifter, while doing exploratory disassembly (w/o getting destructive). At the worst, I'll have to double down for a brake lever....
