How to override a class method without __name__ attribute (model, wizard or report)?

each with its own database and sharing a common code base (every instance symlinked to that common code base in order to avoid files duplication)

You can start different processes from the same code base, there is no need for symlinks.

however I want to allow every instance to have customized reports… therefore the “standard location” for the report is not an option since one instance would overwrite the other one

Customized report can be stored in the database directly by editing the ir.action.report. The template in the database has priority over the file.
Also you can have custom module activated only for a specific database.
