A possibility, yes. But the problem is that from the protoss POV, in too many cases Kerrigan either lied or had her hidden agenda. They're not going to listen to her. As for using a fake face and all that, it wouldn't work because Ouros already did this by using Tassadar's face. Given her ascension, the protoss would know Kerrigan is doing the same thing.

As for settling old scores, there have been those who argued that the only way this is possible is if she loses ALL her psionic powers, even those as a terran. But after HotS, even that might not be enough. Remember, the primal zerg don't have psionic abilities, yet they proved a challenge all the same on Zerus. On the protoss side I guess maybe they could risk it if she lost all those psionic powers though.

On the terran side, you're right in that Mengsk would try to cover up his crimes, but remember he didn't hide everything. One of the reasons for the Dominion salvaging operations on Tarsonis (in WoL) was to discover more Confederate military secrets, but Mengsk probably did factor in the possibility that the Confederacy picked up something about what happened at Tarsonis all those years ago. I also wouldn't be surprised if Valerian told the Dominion people what his father did back then, along with leaving Kerrigan to the zerg.

Furthermore you have to remember that there were already terrans who suspected what happened at Tarsonis wasn't what it seemed, even BEFORE Raynor made the broadcast of Mengsk's crimes. If you looked at the UNN broadcast after "Cutthroat," documentary producer Tilosky made a film called "Imperial Dawn," and claimed that Mengsk ensured the destruction of the Confederacy by destroying Tarsonis. He stressed that it was a bit TOO covenient that the zerg just so happened to destroy the planet holding the corrupt government that Mengsk spent almost a lifetime trying to destroy.

The bottom line is there were those in the Dominion who felt the numbers weren't adding up, and the zerg timing in assaulting Tarsonis was a little bit TOO perfect. But there was that "missing piece" that no one knew what it was, until Raynor broadcasted it in the "Media Blitz" mission.
