Seems neat! I'd push for a form other than a house cat though- possibly something that actually related to the fact that the godling is composed of many different minds (the players) acting in unision. Could almost go the Hindu style and have multiple faces, though I imagine some would find that odd.

Other thing to do might be to decide on some specific portfolio or area of interest to the god and have that influence what form is chosen. For example, a god of storms and the sea would have some really strong imagery to fall back on, as would a god of poison (snakes, venomous insects, etc) or any other number of things.

Personally I'd lean towards something decidedly more otherworldly looking as far as the form chosen, but that's just me.
