I think you need at least 24A here.
The discharge will take as long as the charge, and you aren't outputting
any current during charge.

I suppose you could run another inductor antiphase, using a current mode
controller, but this is getting a bit esoteric.
Your filter caps will have to be rated for 12A ripple current at the
frequency of interest, and that alone will be non-trivial.
