I don't think they could win. Neither of them can teleport, so they can't get a cheap hit on Cell like Goku did. Cell has every technique in the book, and Dabura's spit can't do anything; Cell can simply discard the affected bodypart, regenerate, and keep winning.

If Cell keeps messing around like he did against Goku, he might lose. But if he gets to business and just starts blasting one of them, it's just a matter of time.
