[@Expllo]  how is this for a Nimble Fury debuff? So he can still use the levitation ability until it reverts to it's base form.

"This ability taxes a large portion of spirit energy and can only be used 4 times in a usual battle. Use of a fifth time causes the Zanpakuto to revert back to it's base form for 10 turns."

I was also wondering (and stop me wherever you want to) if it would be too OP for Enlightened Spirit to be strong enough to lift him. So he could stand/hang off of it. 

The changes to age you requested have been made to the sheet already.
