I'm looking at supercaps. I appreciate that a few people have suggested
this, though I don't know yet whether it could be done economically.

I think the answer is really quite simple — and very expensive: capacitors!
I have a fence charger that charges/discharges six joules every second or so.
I have studio strobe lights that can charge/discharge nearly 5,000 joules in
under ten seconds.
Other than the magnitude of energy that is moved about, these applications are
perfectly safe, and no BMS is necessary.
So-called super capacitors have come down in price dramatically recently,
although they are still a couple orders of magnitude more expensive than
batteries. But your application sounds like it needs capacitors, or you may end
up paying nearly as much in safety, failure prevention, and battery management.
