I think the best COTS solution would be to use a pair of round / keyed VersaHubs in there. You don't really need to bolt the hub down, since all the hub is doing is keeping the 1/2" axle concentric with the 1.125" hole. Just be sure everything's retained and can't slide past each other too easily. Would this mess up the gear spacing (lengthwise, along the shaft)? I dunno.
If you can do any lathework, a 1.125" OD, 1/2" ID spacer wouldn't be too hard to make, or even a single piece shaft with a 1/2" end and a 1.125" end. But I suspect that's not an option for you.

I am using the clamping gearbox to drive a sprocket. I thought it would be less complicated to go dead axle since the gears and the sprockets have a bolt circle anyway, but it looks like it may not be.
Adding a hub in there would work, but it would push out the driven gear from full (or almost full) contact with the driving gear to .28" (56%) contact. That may be enough, but it is a little more risky.
While I theoretically could make a custom spacer from cylindrical plastic stock, it seems like too much effort and a source for misalignment.
