Other thoughts or ideas?

Where are you thinking of the tape measure in this scenario? Putting it right against the tower probably wouldn't work. Putting it a few inches farther from the tower than the CoM should work, though. If you have a roller higher than the CoM, the force from the roller should provide a balancing torque to keep everything from flipping over. Definitely need to Free Body Diagram it to make sure everything balances, though.
My prior thought was a three point lift, which would guarantee levelness, at the price of much more complication. I like your idea a lot better since we'll likely have something over the bumper for boulder grabbing and defense manipulation anyways.
