Don't the Jews kind of look at Christian-Jesus that way already? What about Muslims? All 3 religions started the same, then branched off from one another. Perhaps the anti-christian-christ will actually be the pro-muslim-christ.
Heck, perhaps we'll get a pro-christian-christ, a pro-muslim-christ, and a pro-jewish-christ all at the same time. Then, we just stick them all in Thunderdome together. 3 men enter, 1 man leaves!
