Nice try. They're the Amiga ports of NetBSD and OpenBSD. Thats still not quite the same as "Amiga Research Operating System". If that was valid, then anyone could call their operating system "AmigaOS".
Please remember "AmigaOS" trademark was crafted in late 90s. Commodore never called it AmigaOS. It was nameless until modern times.
Or, why not try and sell PCs as "Sony Research Playstation 3"?
I think proper example would be "Playstation Research Operating System".
You should not use Amiga OS -> Amiga "R" OS intuition, it just is not right.
