This drive shaft will direct drive one of the stock wheels, and a belt connected to this wheel will drive the other wheel. What I'm concerned about is what we will use for the larger drive shaft, and how the wheel will be direct driven by this shaft.
Here's a easy way to direct drive a 1/2" hexed wheel.

Buy some 1/2 hex rod from Vex Pro. Also buy 4 each 1/2 Hex collars. Buy some hexed banebot wheels. cut the hex shaft into 2 each 3.5" pieces. Using a lathe drill a .312" hole 1.25 deep. Make two shafts. After drilling take a hack saw and cut a .3/4 cut down the middle of the shaft.. The hex will go over the cim shaft, then put a collar on and tighten. Slip two banebot wheels on the shaft and use a second collar to hold the wheels on.
