Great question!
A quick answer is yes it can be done using pairs of rare earth magnets. Neodymium or stronger, in pairs to generate the opposing force, and other pairs to locate.
the exact layout will change for each subject.
Now add 4 rare earth magnets to the underside, one side south down other side north down, then add 4 to a base with the opposite polarity... and viola, one floating hover craft.

Nicely done, and HUGE!
Just an FYI SR-71A Build # 61-17967 now sits at the the 8th Air Force museum, Barksdale AFB in Louisiana. She went back to Lockheed Palmdale to be refurbished in 2018
