I hope you're right. Christian vs Jack Swagger would be an excellent feud, as we've already seen that the two can put on some incredible matches from their ECW days. However, if Swagger and Cole lose their tag match against Lawler/J.R without some sort of outside interference or a Swagger face turn (and a clean Lawler/J.R victory is the most likely outcome given that this is likely the sendoff to that feud), it's going to make Swagger look incredibly weak. Otherwise, if Swagger face turns, as has been teased in the past, that also invalidates him as a candidate. Therefore if Christian wins the title,I don't think he will be facing Swagger for at least a few months. However, I could see him feuding against a returning Chris Jericho, which would be excellent. A Barrett or Rhodes feud would also be entertaining, although it would be uncharacteristic for the WWE to take a chance like that.
But if Christian wins the title and has to feud against Mark Henry, god help him. That will be a guaranteed dud of a feud and the kiss of death for Christians title reign and his chances of ever earning another.
