This is something I've been investigating. If one had a gateway that spoke Reddit's API, the apps wouldn't even really have to pivot, just change the API base URL.
And in theory not even that. As long as the traffic can be redirected to a different server it should still work. In practice, however, at least Apollo has some server-side components so it wouldn't be totally plug-and-play without developer support.
Sadly, I'm not sure how to get in touch with the developers/users who may be interested.
(I've also heard that someone's working on a Reddit/Lemmy gateway, but I don't know who they are or how far they've gotten.)
