So, what would be needed to start a real, honest-to-god replacement for Android/iOS? You'd need a whole governance structure for your project so it wasn't controlled by a sole entity. There would need to be assurances that using your project was stable long-term. That there were adults driving the bus, and that everyone could use the bus, etc. You'd need to provide a roadmap for everything needed to be built to replace Android, piece by piece. (I guess you could re-use sections of open source code, but some would need to be rewritten from scratch?) You'd need to contact developers, vendors, service providers, etc, the whole ecosystem existing around smart phones, and get them on board with your project. Sell it to them as "no longer being answerable only to Google and Apple". You'll also have to provide alternative revenue sources, as they may depend heavily on Google and Apple services for their revenue. And then you need to find people to do the work, and get paid for it. I'm guessing all this would take at least 6-12 months to get off the ground and some serious capital.
