Aliens

...I would totes be down for aliens! Have them be events like Redd or something!

I Totally want to see an Alien Crossing game;

HECK; If Nintendo wanted to; they could even call the extraterrestrial Currency Whistles[Obligatory Bells & Whistles Joke]

I Wonder What Aliens could be featured in an Alien Crossing Game. . .

Probably ones that are in the Public Domain such as Grey Aliens. . .

I think it would be best as a separate thing from Animal Crossing but in the same genre. The concept sounds cool and interesting and can really be built upon as it's own game.

As for AC, I could see them doing some space themed villagers. I know Ione already exists, but we don't have a villager who wears a space suit like Knox wears knight armor. (unless that is something Nintendo is moving away from) Also, having a villager or NPC with antenna would be adorable. Maybe they could be based off of a green snail or something like Piccolo from Dragon Ball.
