Doing this all from scratch will definitely give you lots of great CAD practice. While people are mostly critiquing the design itself here, the model looks good.

As for the design, yes 148 had their "nonadrive" again this year, but it wasn't really. They removed the sideways omni wheel in the center that gave them omnidirectional capabilities because (I think) of the way their driver liked to do things. So this drive train will not be able to strafe unless you swap in mecanums or add a sideways omni wheel (or do something else).

If you're going to have the gearboxes offboard, you really should combine each side. You will have half the gears and half the pneumatics, and you can use standard Super Shifters which make it waaaaaaaay easier to change ratios. Unless you go with mechanums. Then you need to drive each wheel separately.
