Coma, unfortunately for Mia, your number one doesn't make any difference. She is stuck with whoever is, as you remind us in number two, America's favorite dancer. Now, with that in mind, I think you may be right about Travis, but not for the reasons you mention.
Having not seen Celine's show, I cannot say who I think is best suited for it. However, making a guess I think Travis would do well in the show because he fails to wow me as a performer. His technique is outstanding, but his lack of personality as a dancer will allow him to blend in with the rest of the ensemble, which I imagine will be required of the winner.
"I am open, and I am willing,
For to be hopeless would seem so strange.
It dishonors those who go before us,
So lift me up to the light of change."
