Could you see a Romney-Huckabee Unity Ticket?

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.

What exactly is being unified here? Romney is socially conservative enough that he doesn't need to pick a religious right figure to solidify that, otherwise he would have picked Santorum as a unity VP in 2012.

You could argue that his loss in 2012 showed that he failed to impress the religious right.
