So yeah im hoping i can do this with a minimum on complexity.

We tried that, but it wasnt too sucessful. We also tried taking urethane round stock and turning it on the lathe, but that didn't work too well either, atleast at the hardness we wanted. (We ended up with custom molds and pouring the rollers). If you went with a harder material, it might be possible.

It just seems like you are simplifying one of the easier parts of building them, and would require tons more rollers as well. I definitally see the same problem you do, with the strength of whatever you use as a tread actually holding it up.
