This mod looks just AWESOME ! I like the idea very much !
Here some suggestions:
-the starfish island should be the island of the most rich persons in Vice City, and there should be outside-parties, with expensive car, hot chicks and drunk men. (or maybe a mission like that)
-maybe a church ?
-malibu club should be closed, so a new club will take place there.
-the Vercetti Estate should be redesigned
Good Luck ! And I hope I will see news soon
