SDP-SI sells "fairloc" hubs for their gears, which are like integrated shaft collars that allow you to leave the shaft unmarred. Something like that would be good for interfacing a brushless motor.

That's the big issue.
Once I knew what I was looking for in a controller and in a motor it became pretty easy to find things that would PROBABLY fit the requirements. [1] But a lot of the issues I ran into were because the specifications don't involve things like "torque" and "rpm" directly and instead involve new terms like "kv" and a handful of constants that I didn't know.
[1] Was looking sensorless brushless for cost reasons, ended up changing scale on the project and am using a pair of tiny brushed motors that, even with controller, come in cheaper than the motor.
