Could you see a Romney-Huckabee Unity Ticket?

No.

1. The two are ideologically incompatible. Romney is an Establishment type; Huckabee is a right-wing populist. Ideological similarity matters for much; it makes gaffes less likely.

2. Huckabee doesn't swing any states that can make a difference. Huckabee polls badly outside of states either in the South and states unlikely to ever vote for a Democratic nominee for President.  If Romney thinks that he needs shore up Republican support in the South, then Romney is dead in the water for 2016. The only state in which he could help that is a conceivable swing state is North Carolina... that an absolute must win for the Republican. Although people living within the Blue Firewall (Atlas Red) can vote for Southern moderates they don't go for Southern reactionaries.

3. He has no experience in foreign policy or defense, areas at which Romney is weak.

4. He has no experience in any part of the Federal government -- not a Cabinet post, not the Senate, and not even the House. Contrast Dick Cheney, who at least offered that.

5. He has no military experience. Although Democrats can get away with having nominees with no military service, Republicans can't get away with having both the President and Vice-President lacking military service.

6. He is a right-wing Southern Baptist. He will have trouble in appealing to the values of people of dissimilar religions.

Romney/Ryan? They didn't lose because of a lack of military experience.

True. But either of them being a military hero would have helped.

It's possible but unlikely.

Huckabee currently polls poorly, and it'll be a ticket of two white guys in their 60s who have been out of office since 2006.

However, Huckabee does help with groups Romney is weak, such as working class voters.

If there is any sign of any split between the Corporate Right and the Religious Right they could be on the ballot together. But such would indicate a huge problem in the GOP in which preserving a coalition means more than winning the 2016 election.

I do not see that happening.
