I also had a thought along this line, but using magnetic levitation in air or vacuum. The actual bearing would need to be a lightweight hollow sphere made of a magnetic material. The electromagnets used for levitation would need to be fast and strong enough to deal with vibrations and accelerations. Probably cost >$100K to develop.
