He has the Destruction, Good, Law, Nobility domains and I suppose his inquisitors can pick conversion but are there any other ones that his inquisitors are allowed to pick from in any of the published books/supplements? It may be that the gods in the the other supplements (Dragon Empire etc) don't get access to inquisitions.
You could take conversion since it says any deity and black powder and spellkiller says any that your GM will approve of, but as far as I know only the main inner sea deities have been given inquisitions, but outside PFS you can always talk to your GM about it.
