Wolverine is their only real chance. If he gets a lucky swipe at Thor's jugular or heart, it's lights out.
However, Thor isn't stupid. He'd realize Wolverine is the only real SLIGHT chance they have in hell and either BFR him or fry the flesh from his bones with energy attacks.
The rest of the X-men on this team can't even hurt Thor in any meaningful way. Magma, Sunspot, Colossus, and Storm are literally dead weight.
Iceman and Cyclops annoy him for a few seconds before dying badly.
