Ah bummer, I would like a smug villager like him but even though I have the whole day off on 9/4 I don't think I can go online with ACNL the day before when you'd need somebody to come talk to him.
I've never done it myself for villager trading just making it KK slider day, but I guess you just start up your game and tell Isabelle you need help when she says the current date then she'll let you change it to 9/3 and he should be in boxes. But you run the risk of flowers dying or whatever else might happen it would be like you didn't play the game for two days basically. I lost a villager named lolly one time doing that.
Anyway... I have to get going to work good luck with Kidd.
