In all seriousness though, at the end of the day this is just a meme started by a move used in the game and how awesome the concept of suplexing a train was. If SE does add such a thing to the fight then it'll obviously be fanservice, but I wouldn't get my hopes up if I were you guys.
To be fair FFXIV is /literally/ 'fanservice the game'. We've gotten so many tongue in cheek nods to memes, most of the FATE's are legit puns or pull from internet culture, old games, and other silly content at this point that I'd honestly be surprised if they /didn't/ add something. Even just a tiny one off dialogue piece that mentions how silly it would be.
