Interesting idea... but if you used taper-roller bearings you'll still need two bearings. But, the nice thing is, if you use a taper-roller and a straight roller bearing together, the taper roller bearing can be a good size (to handle the weight), but the straight roller bearing could be a very small one, i'd guess you could go down to something like a 1/4~3/8" shaft at the top of your drive modules. In the end, I think that combination of bearings will still beat out two big ball bearings for weight/performance.
Just remember, the only thing that holds taper bearings together is force, they don't stay together on their own and only bear thrust load in one direction.
Please pursue this, I'd love to see what you come up with cad wise. Way to think outside the ball bearing!
