Maybe worthy ... but probably a fools errand.

Think carefully about what you're asking for: a model which is 
expressive enough that it could embed _any_ other model that anyone 
might reasonably adopt for _any_ other reasonable purpose, without too 
much pain or effort.

I don't believe there's any such beast ... at least, I've never run 
across one. Even within the restricted domain of programming models, I 
wouldn't expect there to be one that'd have much chance of qualifying 
as both universal and universally acceptable ... would you?
