Question, why would you ever want to read their air dodge and follow up with a grab if you have that much free time. There are much better options to hit them with out of their air dodge than a grab when they land -_- Unless you're saying only grab twice, the first setup and then one follow up grab. People figure it out after the second time.Try doing D-throw and U-throw "chain" grabs instead. They're MUCH better. All you have to do is read the air dodge, and grab them as they land. It's epic. It's really really good against characters like Snake, Marth, and DK who hate juggle traps. And when you do them, you win 9000 awesome points (well...at least in my book).
Use Forward Throw to get people offstage. Or for dealing damage.
Also, do you even play Luigi?
