I would like to gradually expand this to include more sims, especially the early DLC sims that don't have preset weather outfits and some of the Maxis gallery sims, yes. Probably not all of them, since some are from different timelines or don't fit the current game, but certainly some.
Aliens Reloaded is currently my priority, though. I'm working on a very big update for that one right now and hoping I can get it done before the end of the year.
