Many attempts have come and gone to make Gammu AI into... anything.... and have failed.
I don't think the faction is going to get massively renewed interest any time soon, or even an official faction for that matter. Recall that Omicron Chi was injected with some 'Gammu AI content'. No really batted an eye, least of all Omicron factions.
I understand that this is a controversial proposal, but I think Gammu AI as a PvE faction used for missions and events within the Omicrons could actually be a neat way to make them useful. We could also probably quite easily write them a good storyline, and make them easier to use as a roleplay entity, this way.
