I think you should clarify whether you're asking if such a mod can/would be suppressed for some high n mighty reason, or if the tech modification process can be automated within a mod. So in the case of the automating, can today's mod cover future factions, right? I think the answer is 'no' to either question. it would've been nice to make one release and then just enjoy the fruits, but no you would be looking at periodic updates if you want your users to be able to play it as you intend.
That's based just on what I know of mods in general. It might be possible to develop an adaptive mod, but it would be more involved than you imagine, and not worth the trouble. I think anyway the result would have an assembly-line feel to it.
