All FT logic aside I love this ending!!! XD Emotionally intense, action packed, just about everything you want from a good ending.

It's arguable that Jellal can somehow stop the Etherion. (I know, I know it's basically an all powerful cannon again "arguable" lol) He was on the magic council for however many years, aswell as (arguably) one of the strongest mages alive ATM. Not to mention that the tower of heaven absorbed Etherion and converted its magical power to Jellals favor, which He spent basically his whole life trying to accomplish so he might have a trick or 2 up his sleeve.

As for fiore being wiped out by Etherion, well it's kind of a 2-sided argument, it's most likely going to be wiped out regardless so it might depend on whether you want to try and kill the dragons while the negative is that it would wipe out fiore, or not use the cannon but the dragons might wipe out fiore anyway. I guess it's all how you look at it lol.

But then again this is all rambling lol if any of it actually happens we were expecting it xD
