Have you tried the National Greek Alliance?
It was formed last year with the governing bodies primarily non-NPHC Black GLOs, but if you look into it, I don't see why they wouldn't accept multicultural GLOs into the fold, especially since they couldn't or wouldn't join the NPHC.
The website is

The email address is greek_unity@hotmail.com
Good luck to all of you.
