I need to extend the UML metamodel in a purely additive manner: I just
need to subclass a few metaclasses to provide features that UML itself
does not have. I considered the profiles and stereotypes route, but it
is just too limited for my needs (because I need to create new
associations between metaclasses, and all that stereotypes let me do is
to add properties with primitive types - is that correct?).

However, after going the heavyweight route, I realized that even if I
was able to add elements of my new metaclasses to a UML model and
persist it, I would not be able to load the model as those elements
would not be understood when loading the resource. I guess that should
have been obvious were I a bit more knowledgeable about UML.

So now I am stuck. Is there a way of doing what I want so that:

a) I don't have to re-implement UML and can basically extend the UML2
API and implementation

b) models created with my metamodel can be read by any tools that can
read UML2 UML models
