Looking For A Way To Side With The Volkihar Clan Without Being A Vampire
Around five years ago, I played a run as a Lich character, and I thought it would be cool to bypass becoming a vampire to join the Volkihar side in the Dawnguard DLC because I'm already a creature of evil, let's do some evil, and I don't think the blood would work on a skeleton anyway, but I didn't find anything and I had to pretend I wasn't a vampire even though I technically was on a gameplay level. Well, I'm in this spot again.
This time I'm playing a run as a Succubus, and it's got me looking for a solution to this little roleplay conundrum again, but I'm struggling to find a mod or just a way to bypass becoming a vampire in this scenario and play through this questline, five years later. I was wondering if there is a flag I can set or a mod I may have missed that allows for the roleplay I'm after.
In short: Looking for a mod that lets me join the Volkihar side of the Dawnguard DLC without my character actually being a vampire, due to my character using a different modded affliction/alternative form mod already. For roleplay reasons mainly, so I consider this request a success if I can just get all the vampires to stop sending me to Harkon for 'not having the blood' and the ability to continue the questline without having to be a vampire on a gameplay/mechanical level as I don't want to have the gameplay buffs/hindrance of being a vampire since I'm doing something else. I'm not interested in being a hybrid either. I don't need dialogue edits or anything (though they would be welcome if they exist).
Edit: I'm not asking for roleplay suggestions or roleplay alternatives. Please do not continue to suggest that I should join The Dawnguard instead, become a vampire lord, or not do the questline. I am asking for what I put on the tin literally. This is a game mechanic request.
