Shouldn't be to hard to rig up with just brake cable.
Switching steen levers isn't as hard as I thought it would be.
The only possible problem I see is not having enough travel or pulling power with the cables.
Correct, that is the problem with trying to shift with a handlebar lever.
Not near enough travel or hand strength to move that shift mech like it is for say a 3-speed internal bike hub.
You could fashion a long shift arm to the shifter output and have plenty of mechanical advantage to shift with a really long push / pull lever sort of like Rat Rod comics used.
Then again if you have some seriously long strong arms you can just reach down...
Hehehe, I love those old comics.
