There is a mod, that makes Wyll basically a tiefling with their perks, like fire resistance, advanced dark vision and a spell selection (I think from the Zariel spell list). He also has the fangs and tail.
I would love that. And then you should be able to tell him as a tiefling, how foolish he is, to complain about his horns to me.
Nice one fylimar. Modders are so creative.
Wyll is very close to Tieflings; his purpose in life is to protect and avenge the vulnerable and they are extremely abused as a group.
The slight difference I would make is I wouldn't make him a Tiefling exactly, like not giving him a tail, because I think it's important we can see the change is not as dramtic as he imagines when it first happens, and I feel like that moment after he has been transformed, when he is embraced by Tieflings in the form of Karlach is a really important full circle moment for Wyll. The change makes him partially a devil, exactly lwhat Tieflings are often accused of, and the first person to tell him or remind him that the important thing is
who is is a Tiefling.
It would be great if you could have that moment with him specifically as Tiefling fylimar.
I always say it's one of my favourite moments. It's really touching and a bit flirty. I feel like part of the reason Wyll gets used to the change so quick is an amazing girl like Karlach tells him that he actually looks great. Which I don't mind because he's my best mate and trustworthy (and I definitely don't mind if I'm playing as Wyll

).
