After fooling around a bit ingame, I think I may have gotten it.

It’s not the most damaging combo, but i’m thinking that an assist like Unibeam could extend the Bon Voyage version, but it would take really precise activation because the opponent wont WB after a second launch. At the part that I put in (these), you have to delay it and either:
-Walk forwards and catch the wallbounce (if your not in the corner)
-Catch the wallbounce from inside the corner
This is just because where the enemy ends up after the first “Bon Voyage” and where you are varies greatly from where you start. Due to this, I recommend starting from center field.
