Will never work. As much as anything there's different hardware routes.
Why would aros or mos want to adopt the ultra expensive/10-20 year old performance route? Doesn't make much commercial sense at all to begin with, and even less sense to drop affordable/easily obtainable hardware for something that's much more expensive and much less powerful (in the case of aros at last, mos h/w I guess isn't too dissimilar).
There's also the fact that one system in particular is trying (albeit comically) to portray itself as a professional business (which is ironic as its attempts to do so have been the most comical parts), whereas the others (especially aros) are done soley as a labor of love. Somewhat incompatible agendas.
Not only incompatible agendas, incompatible intellectual properties. MOS folks, in theory, could (and more then likely would never do so) change to open source their code. Portions of OS4, OTOH, has tainted code with IP belonging to who ever owns (Cloanto?) AmigaOS (68K) because the OS4 original core Devs had access to the AmigaOS 68K source code when developing OS4. Only way for a unified OS that includes OS4 is for everything to swing to OS4 as open source and that would surely end up as a full blown disaster. Basically, merger of MOS and OS4 is impossible.
If the combine communities want a single unified OS, it will have to be based on open source (at least to start) with whatever code can be legally ported with clear intellectual property ownership and leave the closed and or tainted code behind. Good news is such an approach will leave certain legacy issues in the dust bin of history.
Now that will more then likely suck the last of the oxygen out of one or both camps but if you want a new beginning, you have to bring the old journey to it's final conclusion. Sadly, that can be too painful for some to do.
Alrighty, back to lurk mode...
