That will hold it from twisting side to side, and hopefully, the one up through the bottom, toward the front of the vehicle, with the nut inside the receiver, will hold it from rocking up and down on bumps.

I'm not sure that you'll get enough deformation of the receiver to properly clamp on that tube. Maybe you will, but you'd have to get your tolerances really tight on the tube.
Another option - weld a nut on the front-side of your 2" tube. So when your carrier is inserted into the receiver, you can crank down on a bolt that's hidden underneath the vehicle to tighten it all up.
If you're certain you'll get enough clamp force with your method, that's cool, just figured I'd offer up some other ideas.
