Questions like these always need more information then just a can we do this phrase.

I didn't think it was all that underspecified. The standard deviation on the amount of torque seen by FRC drive trains isn't all that big (essentially all of them are going to be on the order of 10 ftlb, unless you're running a ridiculously light robot or ridiculously big wheels). Say 160lb robot, wheel COF of 1, 4'' wheels. That gives a torque-at-shaft during wheel slippage of ~13 ftlb if you're running each side chained together, or ~6.5 ftlb if you're running each wheel off its own motor.

Coupler is, as mentioned, just a hex sleeve sitting on the ends of both shafts. Not sure how the specifics of the shaft support affect anything, so long as neither shaft is being supported by the coupler (which you clearly wouldn't do with a sleeve on a shaft taking a large load).

I know that for reference VexPro's gears all have 1/2'' of engagement on the shaft, but I have no idea how conservative that is.
