It's doable, but 3 phase motors can boost on regen down to almost 0mph, so the half bridge boost out/buck in one inductor design pretty much covers all the bases. The capacitor version will be more complicated at a minimum, and has more opportunity for shoot through, and seems to have about 2x the current spikes on the battery in boost mode (uH=uF).

What problem are you trying to solve I guess is a fair question?

Worth noting that interleaving topology does a nice thing for inductors in that you can quasi-parallel them without the loss in uH (and smaller cores seem to be more readily available).
