@DrewDad,
Not really.
The anyone-but-Romney faction is looking for a conservative firebreather that will promise (whether or not he delivers) to make huge sweeping changes. They are not focused, above all else, on defeating Obama.
To be fair, some truly believe that a Gingrich or Perry can beat Obama.
I would love to see someone more radical than Romney win the election, but I just don't see it happening. Those who disagree with me often cite that the conventional wisdom was that Reagan was unelectible and he won in a landslide.
Unfortunately, the current crop of GOP candidates contains no Reagan which is to say someone who you could strongly disagree with politically, but would have to admit was likeable. Clinton had a similar knack.
Even people who often agree, politically, with Gingrich can't stand him, so what chance is there for someone on the fence to fall to his side by virtue of exuded charisma?
