Now, I think a 6-mecanum drivetrain could work, provided that the center mecanums were matched to opposite corners--that is, the FL and the RR mecanum wheels are matched to the CL and CR mecanums, and are oriented the same way, either via chain or via programming, or some similar setup.

OHHHH. This robot's a square, I thought the left side of the picture was just cut off, and now it makes a whole lot more sense. Thanks!
And I think you're right, but I think it'd be a mess to get the powers ratios right, because you've got 2 wheels on the ground fighting one. The weight balance would have to be super weird, or there would need to be a lot of math with traction forces, power draw, motor controller and motor curves, and stuff so you could manipulate power ratios so the forward components cancel when you strafe(and the sideways components do when you don't).
