Are you referring to a ball shifter, dog gear shifter, or something else?

If it's a Ball shifter I would think probably not since the plunger inside the shifting shaft would likely be too big to accommodate 3/8" Hex. Can't speak to the possibility of doing it with a dog gear shifter though.

IMO It would probably be easier to adapt a 3/8" hex onto the output end of a Vex gearbox than it would be to make a custom shifter for it. Not sure if that helps for your specific situation though.
