More feasible obviously, the question is if Trevor would have that split second timing. I feel it's a little optimistic to give him that.

Overall...

-I think Raiden is being overhyped as a soloer. I got all no-damage S-ranks on Revengeance at every difficulty level. His AoE is nil outside of immediate melee range. His thing is efficient single target elimination, which is difficult to pull off when two thirds of the enemy team can bring people back up and all of them are midrange combatants. Same for Gordon unless people bunch up for a rocket.
-Raiden IS a raidboss. It's going to be a long, protracted battle trying to bring him down and he's gonna have to run down the other team's MP in turn as well. Neither side is going down easy in this fight.
-Gordon is critical to the opening minutes (yes, minutes -- I said this fight goes long and meant it) of this fight. He's gonna draw someone off to deal with him, possibly two someones, and that's the make or break point. If Raiden can take advantage of the split focus to obliterate everyone else, his team wins. If JC's team manages to hold out until Gordon dies, the 5v1 (sorry Tingle) becomes way too much to overcome.
-I do think it requires two someones to deal with Gordon. Sypha and Aigis could beat him solo, but the thing is that'd take a lot of time and they can't afford that. It's more likely that one of the two plus Crono or Trevor has to peel off. That leaves the other, plus Eunie, plus whoever of the fighting men didn't peel off to check Raiden for a bit.
-Losing Pamela is brutal for this matchup. I think she dies because even if you're a Castlevania disrespecter, the Vampire Killer specializes in slaying undead and put down the reincarnating Dracula. Pam is not Drac. Asking her to survive against Trevor is just infeasible.
-Ouroboros Eunie is key for this matchup. You know all I said about Raiden having no AoE and so on? I would instantly write the enemy team off regardless if they didn't have dozens of illusory copies of themselves clogging up the library, with several of them inflicting debuffs. Some of them are mostly irrelevant -- Raiden is so strong ATK Down doesn't stop him from killing. Some, however, are crippling. If Raiden is slept then the other team gets to swarm Gordon and reapply Limitless Resurrection then restart the fight at leisure, which is absolutely huge. I don't know if this trick works more than once or twice (unless Raiden gets super frustrated and goes Ripper Mode and starts scything through everything), but even one chance to hit Raiden with Luminaire, Heritage Liberator Palladion, Sypha's ice blades and Trevor's pachislot Grand Cross is a huge deal, particularly when they're all boosted by a Power Ring. He's very tough, but he's not 'no-sell that much damage' tough.
-Team JC has experience tackling raidbosses. Eunie comes from a world where massive beasts and overpowered superhumans alike are a thing, Crono's party took on Lavos, Aigis fought Nyx accompanied by frankly worse backup than anyone in this group (again, sorry Tingle), and Sypha and Trevor fought 4v1 against the mighty Dracula in turn. Fighting an enemy who simply exceeds them isn't new. They faced that kind of opposition before and won. Raiden is a bigger challenge than any of them have ever faced, but their allies are also significantly better than anyone else they've ever worked with.

Overall, these factors make me lean towards Team jRPG Party. It's a very long and difficult match, but they have all the intangibles in their favor. Very tricky fight.
