They could just reference the time that he was the genie's master without the need to actually have a genie. Or they might have a genie appear briefly and have just a minor role in the flashback, which would not require any major casting. But from the looks of things, it would appear that Aladdin story we'll see is from a time after the Genie, and probably will see the events that lead to him becoming a Savior.

Now depending on how long Aladdin hangs around, we may eventually get the Aladdin/Genie story, but I don 't think it would be with this arc unless the Genie has a part in making Aladdin a Savior.
