belt creep is just one aspect of stability. ideally one would want the largest diameters driving each other with the shortest unsupported belt spans, but you start running into practical limits on motor speeds and torque. The belt cannot be made infinitely thin and not have other side effects.The next issue is with the torque and the effects of driving the platter closer to the shaft. It takes more force to accelerate the entire assembly so therefore any force applied to the platter will slow the platter more easily the motor needs to correct for it, the belt stretches, and the mass will oscillate :)...no free lunch in belt drives. Did i also mention, more force more creep?... But here is an experiment you can play. Get a decent motor put in a heavy base and use a bit longer belt to drive your inner platter belt drive on the rim see if it has better speed stability. I bet you donuts to a dozen that using the same motor you will measure the table much better driving it on the rim. Shucks, listen to it may surprise you how much better it will sound if it measures better.
