I did this with my town a while ago
It was strange. All of my villagers were Kidd and sometimes when you spoke to a Kidd a different one would answer lol.
Since it's against the game's design to have more than 1 of the same villager, it was really buggy. All of the Kidds use the same emotions at the same times as well.
Definitely interesting to try out, though!
