On the other hand, the big gear is a 72T gear, so I might be able to replace it with an 84T and remove the idlers. However, I remember on another gearbox I was working with another person, we had trouble with the gear sizes with an 84T.

Switching to belts might be a good solution here. Plus, you'd get a nice efficiency boost.
