Currently, the temples switch rather fluidly from Bane/Bhaal/Myrkul to Cyric and from Cyric to Kelemvor at the appropriate times. There are a few kinks however, the House of the Black Lord in Amruthar never switches back to Bane as far as I know, and a bunch of places might want to have an interim Xvimmite phase. Perhaps that's something to look into if possible.
There is a temple to Xvim in the game in Bezantur but it was never finished. It would be cool if it was opened during the years where Xvim is active. Perhaps even automatically change former Banites to be associated with that temple unless they convert to Cyric instead of just having the Bezanturan Banite temple faction still in existence while Bane is dead.
