Ok so for the conversion to Odhinist with it being a syncretism of Hinduism and Norse paganism I feel like there should be some flavor should you want to go down a different path so instead of Odhinism appearing right away you would have an event chain that if you're indo-norse, unreformed germanic pagan, not zealous, and a King or higher you would get an event with your king getting concerned about how your faith is a religious minority so you could either dismiss it or start a conversion of vladimir the great style multiple choice event chain where your options are Nestorian, Jewish, Sunni or Shia Islam, Zoroastrian, Manchaean, Buddhism, Jainism, Zunism of all things or to consult the hindu bhramins with this final option unlocking Odhinism and all that entails, while with Buddhism you could either become normal buddhist or question why buddhists had been converting to other faiths as of recent and after the monk can't give a good answer you can either throw out the idea of converting to buddhism or decide that the current schools of buddhism are too weak and thus make your own which would have the ability to declare holy wars on hindus and sinners if the one declaring them doesn't have sinful traits themselves, as well as raid with an asterisk as you have to give a portion of the loot to buddhist temples lest you get a piety and opinion malus.
