Yep - that's the vague amorphous idea I had rattling around my head, just described by somebody who knows what they're doing.

As stated - it's getting the initial adoption going that's problematic. Probably pointing out the obvious, but NPR bought my favourite client Pocket Casts. At naive glance, looks like a good fit. NPR already has an excellent group of people who've donated (so whole bunch of people paying already) and with this would give them a way of rewarding them with the adverts removed. Plus think both sides of this would be advocates for still allowing the output to be available widely, and not walled up somewhere.
