Round One: She Clears. Too much power and no one other than the Cuckoos have enough established skill to argue that their skill can pull them past the cosmic amp. And though Psylocke could be just as arguable, her style in psychic fights keeps me from making a case for her.
Round 2: Other than 90’s Jean (who has arguably the strongest Telekinetic shields even around this time), this really doesn’t change the outcome of the battle. I’d argue that aside from 90’s Jean, Dark Phoenix sweeps a lot quicker due to her molecular tk hax.
Bonus: Now this could change the outcome. 4 Cuckoos, Karma, Dani, 90’s Jean, And Psylocke. I could actually argue a strategy for the team to win. They still have a very small chance of winning, but the odds are a lot better for them than individually.
