With Sersi having demonstrated the ability to manipulate Thor's molecules before, without needing any enhancements, I'd say that the match is over within the first second, as Thor turns into maybe a pig (with thereto fitting mind and genetics) or maybe she decides that she needs some potted plant in her loft, so poof, gone is Thor and she picks up a small cactus to take with her hime.
Considering Gilgamesh is an Eternal too, he can perhaps do the same, although I do think I've heard at some point that Zuras said that the best manipulator among the Eternals is Sersi.
Not knowing the full power of Quasar, I can't really say if he can do it, but since people think he's evened up with Sersi, Thor's also gonna be so much splat because of him.
So unless it was a team of Avengers consisting of the weaker Avengers, I'd say that Thor wouldn't be a match for them.

I mean you got guys like Hercules, Gilgamesh, Sersi, Warbird,Jack of Hearts, Quasar and Photon and of course IronMan. Powerhouses who combined would demolish Thor and probably kill him if need be.
Of course Sersi can rearrange living beings. She turned people from humans into pigs before Thor was even thought of. She has fixed up Thor before, something which Loki could not do without a special weapon.
And since you think Hercules is gonna be the toughest combatant to Thor, but at a disadvantage for not being flying, then why not give some credit to the woman who knocked Hercules out physically with a single punch?
