No idea if the lightened gears can, but I would be very surprised if the .4 inch steel gears from AndyMark could not handle the load the FP puts on them, considering people lifted robot-size loads with those gears last year.

To be safe I'd personally forego lightening the final gear even though it's the biggest one.

Hopefully the arm can be balanced with surgical tubing in all states but it's "reverse dunk slamma jamma mode". For the rest of it, the arm is a surprisingly light load on the motor and running it at ~5% power or so to hold it up should be very easy, especially with balancing reducing the already light load further.
