FWIW the 2 CIM Ball shifter with 3rd stage option looks like it has an output shaft that would be extremely simple to create out of steel hex on a lathe. Cut to length, face on the lathe, 3 lathe operations, then tap and you're done. Would take about an hour for both axles. It'd give you 2 spare axles for the outer wheels as well.

This assumes the steel hex fits everything though.
