So the issue is, 

So the plane can generate thrust fine. Which would cause the plane to move off the conveyor. 

Then the issue is that the conveyor apparently matches in reverse the speed of the wheels. So the reason this is a problem is because for the plane to move on the conveyor the wheels have to move faster than the conveyor. 

So probably the conveyor belt would catastrophically fail and or the planes wheels would catch fire as the thrusters go and the conveyor belt approaches infinite speed.

Yeah, I think the bigger problem is *how fast* it would have to happen. In order to counteract the movement of the plane, the conveyor belt would have to go from a speed of zero to a speed that would cause catastrophic failure of the wheels in literally zero time. It would probably look like a nuclear explosion with that much energy released in such a short time. There wouldn't be a conveyor belt or plane left.
