Since they're Gen1/Gen2 AM Shifters, there isn't an 'output shaft' available for direct drive. To direct drive the wheels, they'd either need to add one into their shifter or purchase the super shifters. Option 1 should be doable if they intend to attempt WCD, but Option 2 may be limiting.

Are the bearing blocks COTS items are are they intended to be milled in-house?

Also, in noting the file name of the picture that shows off your bearing blocks -- technically you're using 'live axles' with this setup. Not a big deal for a file name, but you wouldn't want to confuse the two when asking about them.
