But of course a lot of more modern stuff is missing, which would definitely be good to have in a cross-compatible kind of way.
I have long wondered how much the Amiga-like operating systems would slow down once they had to do all the things that modern operating systems had to do.

Memory protection slows down a computer a LOT if it has to process a lot of page faults. That's why I have higher hopes for AmigaOS 3.x than 4.x. Little or no MMU support and a flat memory model. That's what it takes to be a fast OS.
If you don't believe me, try running AmigaOS 4.0 for classics and see if OS 4 running on a 150 MHz PowerPC is any faster than a 50 MHz 68060. I'll give you a hint: It isn't. The 68060 will win most of the time because it takes fewer and smaller opcodes to do the same programming and the MMU support costs processor power.
I see I'm starting to repeat myself so I'll just leave you with these thoughts.

In a way such a thing already exists, in the form of the OS 3.1 API. But of course a lot of more modern stuff is missing, which would definitely be good to have in a cross-compatible kind of way.
.
Even niftier though would be if they open-sourced AmigaOS and merged it with MorphOS. I know it's a long shot but one can always dream
