Mod Idea - Redemption and Falling for Paladins

Playing through BGEE, I had a thought about how to better handle "falling" as a paladin. I know in BG2EE there's a single chance to undo that status, but that seems a bit... severe. In most editions, fixing that status was simply a matter of doing a quest for your order/church, and if they found it satisfactory, hitting you with the proper spell 4th or 5th level spell (blanking on the name).

So the first part of my idea, is taking that "redemption" flag from the Order questline in BG2EE, and adding it to a couple of BGEE quests, mainly killing the insane priest for the Lathander church in Beregost, and bringing the cursed guard captain to the priest of Helm in Nashkel. There might be a few other good choices, but those are the obvious ones.

This soon dovetailed into another idea. What if there were a quest to let a Fallen Paladin make a deal with a demon, a la Dorn, and respec as a Blackguard? That would be a bit harder to code, I would imagine, but would add some more dimension to the Paladin class and its RP factor.

Unfortunately, I'm about as good a coder as I am a singer, so I doubt I'll be making this myself anytime soon, but thought I'd toss the idea out there in case it inspired someone more talented than I.
