Lucky went off to Hong Kong for the park opening there. After he leaves Hong Kong he's supposed to visit Tokyo and Paris.
I never heard of any plans to bring him back to Florida.
I'm guessing that once he finishes his world tour, the Imagineers are going to take a serious look at his technology and see if it can be updated at all, make modifications to the design, things like that. Once they fine tune things, we'll see more Lucky-type AAs making the rounds.
