How possible would a combination gear be? Something with a lighter but still strong internal portion and a steel outer? It might be better than holes for the smaller gears? Like this maybe?

It seems like that would be much more expensive than just making a lightened steel one, however I can't comment on the strength.

Motor question, are the RS 775 and RS 550 standard motor sizes? If so how are they measured?

I think a gear similar to this would be great. I'd make a simple change though to make it easier to manufacture and therefore (hopefully) cheaper. The gear would be entirely steel, and just case-harden the area you have labeled as steel. Keep a small bore through the center for people who want to use small diameter shafts, but by only case hardening around the outside, it leaves the center area machinable. That way you could use whatever profile you wanted in the center without having to worry about sacrificing structural integrity of the gear. Ofc I'd like to see an option for 1/2" hex bore as well for the teams that don't have a broach or a press large enough to accomodate.
