I can think of a few.
From Rayman Origins: Moskito. It'd probably work something similar to Yoshi's Final Smash but with rapid fire knockback.
From Rayman Raving Rabbids: Rave Party similar to Donkey Kong's final Smash perhaps.
From Rayman 3: Armaguiddon which is used in the game's final boss segment. Refer to the first Final Smash to how it could work since it's basically also a flying contraption.
Another one from Rayman 3 could be his Heavy Metal Fist, which could probably work similar to something like Lucario's and Little Mac's Final Smash and give him a huge power amplifier.
From Rayman 2: Shells are commonly used as explosive riding contraptions and are applied to the game in a plethora of ways. You could just use a barrage of them, or make it work like a mix of Pit's Final Smash in Brawl and Sudden Death Bob-Ombs.
Of all the aforementioned, I see the first one being the most likely assuming Rayman is based solely on his Origins incarnation.
Moskito seems like a good, obvious Final Smash.
I'd love to see the Shell as a special attack though, maybe as a mix between the Wario Bike and Charizard's side B.
