I would like to add conversion as a possibility for a UN resolution, but have no idea what the commands for that would be. I've searched python, xml, and so on to no success, so does anyone have any ideas?

Would the code for it be somewhere in the diplomacy files? You can request other civs to convert to your state religion, it must be in there somewhere.

Looking foward to it :)

I checked there, but I found nothing of use.

Maybe it would be something like this?

<Description>TXT_NAME_OF_DESCRIPTION</Description>
<iPopulationThreshold>51</iPopulationThreshold>
<iTradeRoutes>0</iTradeRoutes>
<bSecretaryGeneral>0</bSecretaryGeneral>
<bVictory>0</bVictory>
<bFreeTrade>0</bFreeTrade>
<bNoNukes>0</bNoNukes>
<ForceReligions>
<ForceReligion>
<ReligionType>RELIGION_HINDUISM</ReligionType>
<bForce>1</bForce>
</ForceReligion>
</ForceReligions>
</VoteInfo>

Maybe just replacing "Civic" with "Religion" will work. :p

I was actually doing that before. Unfortunately, the term I used was one I had seen in Python somewhere: ReligionConvert, and that did not work at all.
