I dunno that Celes and Locke would end up together. He has a thing for dead chicks. So I would go with that. Locke becomes a graverobber/grave "adventurer". Call him anything else and he will dig up your grandmother and rip her lungs out.

Edgar would likely make a small puppet named Jigsaw, then test the maral steal of people as he put them in situations relevant to their past, must like the "Saw" films. He really was a son of a bitch.

Sabin would prolly move refrigerator's for a living, after his shorts stint of exercise videos would not work out and leave him as a cultural flop.

Gau started filming some of his strange misadventures with animals on the vault, and now it sounds like himself, Johnny Knoxville, and the lead singer from creed have some film deal in the making. I guess it starts out where the fix the clock in Gau's father's house and then rig it with explosives. They sneak in the middle of the night, mud pie the dudes face, then runs off.

Terra would be come the slothly, overweight, unkempt nursery school teacher from hell. When she finds what "love" is, it drives her insane. The constant drama, needing, pulling on others, and so on. She snaps, and locks herself up in the mountains, where she creates ice sculptors of espers. Before hand, she will loose her hands to a nasty paper cut and had her fingers replanced with large sheering devices. The towns people will hate her.

The mog would have suffered a horrible hunting accident finds himself stuffed alongside Umaro in Gau's father's house.

Cyan would get his own podcast on speaking like a douchebag.

GoGo would form a pop band, and politics have already been pointed out.

Strago would become a champion spelunker and sponge collector.

Shadow goes to right all the wrongs he has made. Sad part is, he started with suicide.

Setzer goes to the Opera.

Realm becomes a master painter then paints and esper from memory. Resurrections of the espers begin, she snaps, and then a CG sequel to Final Fantasy VI comes out.
