Since they have to check with resident services if they can move to your island, they probably wouldn't get the approval cause you already have them. Would be funny to have a whole island of one villager tho haha
You can’t even get a villager that’s currently on your island to come to the campsite, as they’ll wonder why you want them to go there (via amiibo scanning)
I've wanted to test it too when I saw someone selling Sherb here, but I didn't want to waste their time lmao
Maybe next time I'll find an accomplice to do it with me !
I say test it!!!! It's something I've actually always wondered, glad I'm not the only one! I know it's probably not likely to happen.. I just want to see the outcome/dialog from attempting it.
I've actually tried this before! I tried to invite another Katt to my main island for fun and the dialogue to actually invite her never showed up. After the initial 'Hi, I'm leaving' bit, she just kept rotating between the same two-three things that a villager says when moving out. So there's definitely a lock in place to keep you from inviting duplicates.
This does remind me of that time someone tried to fill their island with Raymonds and nine of them wound up as empty plots when the file was loaded
