I think the main issue would be ground clearance with the 3" tubes and 4" wheels.

As Allen pointed out, inline gears, like you have, don't stack up ratios. The gear in the middle doesn't do anything when calculating the speed, so you really have a 30:12. If you want to stack up gear ratios, you have to do something like:
Also, if you are concerned about ground clearance, the wheels don't have to be exactly in the center of the tube. Move them down if you need to.
And remember that you are going to need bumper mounts, but that should be too difficult to add in.
Nonetheless, this is a pretty cool concept, and it leaves a lot of space for electronics. Add in bumper mounts and possibly a bellypan, and fix the gear ratios, and you could have a pretty cool chassis.
