I do like the idea of magnetic suspension; I do not know why you feel that it is a stupid idea. As you built up the mass of your platter then very soon will not be able to hold the heavy platter at a single point bearing. The 20 point still cap sit on vertical bearing but 50 or 70 pound will not as the contact surface per mass ration will be too great. So, to use magnetic suspension in this scenario I fell is very cool idea. Pretend you have 100 pound platter but only 10 of them is being handled by bearing, the rest is elevated by magnet. I think it is an elegant solution as you would have high moment inertia combined with hard path to ground (important in my view).
