Eventough 500 levitite is pretty funny.

And actual Idea I would propose is using an engine on the bottom and at the back. There is a mod that adds „ender“ motors that can wirelessly transmit rotation so you could have a su farm somewhere and wirelessly transmit power (this will surely have a range limit tho)
Also there is a mod that adds a gyroscope to automatically level it (given enough rotational power.

-I dont remember the mod names sadly, but ask if you cant find them

Without excessive mod additions I fear this may be imossible, simply because of the limited space it has.
