i) This is Rauser's M.O. Constantly posing skeptical hypotheticals. While there's some value in that exercise, it's nihilistic to make that your stock-in-trade. 

And it gets to be silly, since you can pose skeptical hypotheticals about anything. "Suppose you came to believe that your wife was actually an extraterrestrial clone of your wife? What would you do then?" What's the point?

ii) In addition, the question is ambiguous. As stated, it's a psychological question rather than a factual question. It's not "what would you become if Christian was false (or demonstrably false)", but "if you came to believe that Christianity is false…" 

iii) Suppose I play along with the question for argument's sake. In that event, I wouldn't become anything. I'd have nowhere else to go. I wouldn't know what to believe. There's nothing else for me to turn to. Nothing else to believe in. 

iv) But here's another response: "What's more likely–that Christianity is wrong or that I'm wrong about Christianity?"
