Could you elaborate further on what a "merge" means to you?
If you need to match elements from two models in order to produce a new model, perhaps you should have a look at the Epsilon Merging Language (EML). You can find more information about it in Epsilon's website:
http://eclipse.org/gmt/epsilon/doc/eml/
However, this would produce a new model and you'd need to load it into a separate editor view, I believe.
Or, perhaps you'd like to import the contents of the other model as-is into your diagram? That's quite a bit more difficult, I think.

Yeah... I was thinking so too... haven't read the docs yet for it but
this might work with some kind of new wizard BUT then... how would you
combine an additional model to the result of the first merge and
represent it graphically? Would this mean having to open a new instance
fo the the graphical editor and discard the old OR will the graphical
editor be able to refresh itself with the new model???
If you generate a new model file, you'll have to open a new editor. If you add the elements from the other model into the model being edited, I guess you won't have to do that.

Yeah... the Ecore tools graphical editor kind of has this functionality
with thier two step "Load Resrouce" + "Create Shortcut" process. This
is another experiment... look how they do it and implementing in my
editor maybe??
That's more like splitting a model over several files, rather than merging two models together.

I would like the user to be able to select which models to combine from
the available models in the workspace and be presented with a graphical
editor that contain all the elements of the selected models.
You'll probably have to write custom code to do that. I think the safest bet would be to call EML programmatically to produce a new model and then open it automatically in a new editor view. I don't think EML is designed to allow in-place merging (i.e. having one of the source models and the output model be the same). However, I haven't worked on that part of Epsilon, so I'm not 100% sure.
