Is it possible to use two .ecore models with one referencing elements from
the other?

Otherwise, I guess EPackages can be used to divide the .ecore model.

I am looking for some benefits and drawbacks from using any of the above
methods.

Thanks in advance,

Of course. The extended library tutorial shows that.

Yes, organizing your modeling into meaningful packages is important.
You can even have interrelated packages, though you'll have to generate
them into a single project.

Well, it's nice for packages to be logical groupings. Some models like
UML have a few hundred classes in a single package, which seems fine. A
few thousand would be way too much in my opinion.
