For Skyrim? No. Modding in general? Never say never.
The problem is that no other games allow for the kind I mods I want to make. I had even more things planned for Skyrim, the biggest one being a Forsworn follower and a Death Cleric/Shaman of Namira. He wasn't a raving lunatic but calm, well-spoken with theming around mushrooms and the belief in rebirth.
All that's gone now. I suppose it's not impossible I could return at some point, but I haven't thought about Skyrim in months and I'm glad I've left it all behind. If/when I make anything more, it's most likely going to be for another game.
