How we can reach Normies with RSS https://videos.lukesmith.xyz/videos/watch/5c864d05-ff1b-473d-86bd-79d8fb011587
Absolutely. Everything you've described, having Normie-friendly apps, push notifications, a single URL to submit, all exists in the current ActivityPub Fediverse. And the software these days is surprisingly good, user-friendly and resilient.
In fact, I've just received a notification from my Fedilab app on Android about this video, and I'm commenting, all in a federated way. There's no reason you couldn't have a podcast on the Fediverse. In fact, there exists ActivityPub designed for audio stuff.
Start shilling more for the fediverse, maybe even post audio/video clips of your podcast(s) on a Pleroma or Peertube account and encourage normies to get on. I posted an audio clip of an SPC-to-OPL3 conversion that bisqwit did in one of his videos not too long ago, it works great.
