-It requires two expensive bearings that are 0.75" id 1" od.
-two of the motors go through 1 or 3 stages of gearing, and the other goes through 3 or 5 stages of gearing.
-It's heavier than my other gearboxes.

It would definitely be cool to build one, and you wouldn't find a gearbox with a lower COG, but I think my other designs are a lot closer to ideal for my team.
As a side note, those bearings only cost a little bit on Boca Bearings, and you could use a bushing if you wanted to.
However, I see why you don't like this. Custom gears are tricky to machine without a softjaw or machinable collet IME.
