Sure, you're adding something to break, but a ring gear that deals with low torque can easily be designed with a high safety factor and one can use "compressible" (like bump stops) mountings to deal with minor flexing.
But I still don't see how it'll be so easy to integrate a hub motor into undriven wheels with no shafts to attach things to. You have to keep brake rotor functionality. There will be an equal amount of custom attachments required except fully integrating the motor into the hub will make said attachments more difficult to manufacture.
