Get someone who cares to throw their weight behind it. You need a way to get developers to a) care about it, and b) do a lot of non-fun work. A Patreon isn't going to work because then the devs just end up doing more of the things they enjoy. It seems like getting a commercial company behind it is pretty much the only way to do it. You just can't tell an independent developer that the UI of their pet project sucks and they need to spend six months rewriting it from scratch. Heck, getting them to agree that the UI sucks is pretty much impossible already! Stuff like this is a lot easier when your primary incentive is "being paid a salary" rather than "having fun with my pet project".
