Not really as ZJGamer said, "time flows differently in the Disney worlds". Outside of gameplay and Jiminy's Journal, Stitch has never been referred to as "Stitch" or hinted to have ever visited Lilo's world prior to KH2, so for all I know he could've visited Radiant Garden or some other original world instead of Hawaii.Hawaii could have fallen to darkness after BBS, leaving Stitch as the only survivor and eventually landing in Hollow Bastion.
Stitch's character in BBS still didn't quite get friendship from what I remember, and him in KH2 could have been sometime after he's been in Hawaii. I believe the best course for a Lilo & Stitch world would be to use the end of the movie's plot with original material (like his Wayfinder and background with Terra, Ven, and Ah-koo, wah!) and backstory from earlier on in the film.
I think if we could get a proper Lilo & Stitch world in a future game it could reenact the climax of the movie much like how Olympus in KH3 is a reenactment of the films third act so I wouldn't rule Hawaii out of the question.
Also we have an unfinished character model for Pleakely after he was scrapped from BBS.
