That's exactly what I built codeberg.org/mrus/overpush and msg.taxi for. :-)

overpush

A self-hosted, drop-in replacement for Pushover that can use XMPP, as well as a wide variety of other services as the delivery method while maintaining full compatibility with the Pushover API and also offering a flexible HTTP webhooks endpoint.
