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.
The 8mm key hub is out of stock on Andymark, so I suggest you get this pairing:

$20 is doable, and this will let your 1 mini-CIM directly drive a KOP wheel. From thereon, just mount one of the KOP belt sprockets to the other end of the wheel and use that to drive the other wheel, as I believe you said.
