Changing faction benefits

[i_am_a_strange_loop]

Hi--playing as a pure mage character, I find it makes the most sense to join the temple of Julianos. However, Julianos is the only religious order in the game (AFAIK) that doesn't offer alchemy services, and neither does the Mages' Guild. How would I go about modifying the Julianos faction to offer potion making instead of item making?

Temple of Kynareth does not offer potions either.

Might be easier to use my Archaeologists guild (mod) and just gain enough ranks to get access to potion making. It will drop your rep with MG a bit as they're rivals but you can easily make it up with a couple of quests.
