Not a massive trend, but I've consistently seen several Harry Du Bois cosplayers at every con I've gone to for the last couple years. Suppose it makes sense, it's really suiting for a certain type of overweight long-haired disheveled guy (like Fat Thor or The Dude in the past).

There's some of it, but I think it's a little to complex to really become a huge FOTM. A lot of people just aren't going to want to do the bodypaint and beyond for Karlach and Lae'zel, and the armor adds more cost and complexity (compare how body-painted homestuckers just wear t-shirts). Astarion is far and away the most-cosplayed BG3 character I've seen, and I'm pretty sure that's more reflective of how easy it is to cosplay "white blouse and leather pants" than his popularity.
