Great Adams Family set, just voted for it. Thanks for highlighting, Ian.
The process is that 10k votes get's it to a sort of round table discussion at Lego. They look at a range of factors, not least how much money can be made from it. That comes down to whether it can be sourced from existing pieces or new tooling needs to be considered, how many sets they can shift, whether it fits into their target market and whether it brings something new to the range.
The only issue I see with them doing it is that it would be part of the Lego Ideas range and, to date, the largest of those sets has been a few hundred pieces. The Adams Family set would need to be a couple of thousand and so is a bit of a risk: The set doesn't fit in with an existing "theme" (other than Ideas) so would be unlikely to appeal to the wider cross section of the market. I'd buy one but I don't think that would swing Lego.
As for Lego becoming more "weaponized" I think that's an inevitability with the franchises they've taken on rather than Lego themselves deliberately looking to include weapons. All the Marvel comics they have sets for involve conflict, same with the DC sets. Star Wars explains in the title it's about conflict! Pirates of the Caribbean, Lord of the Rings and even Harry Potter (I bet the counted the wands as weapons!) all involve conflict. More a sign of society than a sign of Lego following society, I think. On the other hand look at all the popular lines and items they've done that don't involve conflict: Wall-E, Ghostbusters (arguably it does and arguably the proton packs are weapons but I'd go with "tools"), The Simpsons, all the Disney sets, Angry Birds (angry but not armed!), all of them unarmed. And Lego's biggest own brand launch in the last couple of decades? Lego Friends. Not only aimed at girls but not even a handbag swinging feature amongst the sets!
Yes, Lego sets contain more weapons than ever but those are due to the franchises purchases rather than Lego designing violence into sets.
