I think it would work nicely in a prototype like this. My team actually used a very similar frame to this this year, aluminum side plates, cross beams extending to the outer plate, toughbox transmission etc...Anyway the 80/20 worked nicely for us on the cross braces.

The only potential issue with that is 80/20 in comparison to hollow tube, it's very heavy. For an off-season drive train, that would be an excellent idea, though I would recommend against it for a competition bot.
