The easiest way to integrate with a Custom Repository
would be to go along the RDBMS integration.

This would mean, the objects were not created in Zope at all
but directly in the Custom Repository.
Zope would provide views on the Custom Repository similar to
Z SQL Methods (and the associated search interfaces) for relational databases.

You would customize a User Folder.

There are (almost) hundreds of examples for such a task...

It is.

The interface would probably make the content of your
repository "URL-addressable" (see Z SQL Methods and especially
"direct traversal" in this context).
It would create proxy objects (maybe using acquisition)
to present/update/delete the objects in your repositiory.
