Normally I am against mods that change a character. If I hated boxers, I wouldn't mod Cait to not be a boxer, she just wouldn't be my waifu. If I hated Sith, I wouldn't download a mod to make Lana not a Sith, she just wouldn't be my waifu. If I hated vampires, I wouldn't download a mod to make Serana not a vampire, Serana would just not be my waifu. If I hated scientists, I wouldn't download a mod to make Suvi not a scientist, Suvi just wouldn't be my waifu. You get the idea. If you have to fundamentally change important aspects of a character in order to like them, that means you don't actually like that character, you're just making yourself stick with them, and you're changing who they actually are in order to fit inside your idea of what you want, which is not who they are. So normally, I would be against a mod like Really Shadowheart on principal. If you don't like aspects of Shadowheart, don't download a mod that changes who she is, you should just find someone who closer resembles what you're looking for.

However, I think this case is an exception. Because Shadowheart suffers from a writer who directly contradicts himself because he couldn't keep it in his pants later in development, a mod that just removes his act 3 indulgence in his fetishes, and instead keeps the character closer to what the character said she enjoys earlier in the game, it's just fixing a writing error. It's less of a fundamental change, and more of just excising one aspect that is already contradictory and masturbatory from the author that makes the character contradict herself.

I've refrained from discussing Really Shadowheart thus far because this is an opinion and my posts only deal with facts, but since over 45,000 people have downloaded that mod I figure it's worth thinking more about and formulating an opinion on the matter. Which is: normally fundamentally changing a waifu means you don't actually like them, but in this case you're just fixing John's contradictory writing.

Lawful Evil drow are my fav
