I think there is, but it'd need to be very different to existing operating systems to justify itself, and in ways that other OS's can't simply adopt for themselves. In practice that means radical architectural change, and even then you'd re-use a lot of code.
For such a project you don't really want to just adopt existing ideas and implement them. I don't really understand why Google is doing Fuschia for this reason: architecturally it's nothing special. Is the GPLd Linux so bad? It took them this far.
If I were to do a new OS I'd explore ideas like all software running on a single language-level VM with a unified compiler (e.g. a JVM), a new take on software distribution ... maybe fully P2P, rethinking filesystems and the shell, making it radically simpler to administer than Linux, etc. You'd need to pick a whole lot of fights and make a lot of controversial decisions to justify such a lot of work: you'd need to be right about things other people are wrong about, not just once but multiple times. Then maybe if people see it working well they'd join you and port existing software, albeit, the porting process would inevitably involve some rewriting or even deeper changes, as if you can just run existing software and get all the benefits you probably didn't change anything important.
