I think the biggest obstacle StarCraft III would face is that Legacy of the Void is a hard act to follow. Hawki alluded to this in his first blog about Nova Covert Ops. Amon was a threat to the entire universe. His forces devastated the Koprulu sector before he was defeated. Any conflict in StarCraft III would pale in comparison.

With that said, the consensus seems to be that the logical course of action for StarCraft III to take would be to bring back the UED. And if Blizzard hired me to write it, I'd do exactly that. The premise would be that when none of their ships reported back, the UED Council has assumed the worst and sent another expeditionary force.

Horner would be the player character this time. An early mission would be to lead the Dominion Fleet to Umoja to assist Jorgensen, the implication being that Valerian succeeded in negotiating a mutual security pact with the Umojan Protectorate.

Then, Horner would respond to a distress call sent out by Sakai. The UED has deduced that the zerg were able to break their power base on Korhal during the Brood War because they pilfered resources from Moria, and they've invaded the planet to install new leaders that the can rely on to ensure tighter security. So the next mission (or set of missions) would be about assisting the KMC.

At some point, Raynor would make an entrance similar to that of Captain America in Infinity War. Kerrigan would return as well, and it'd be established that she is in fact human again. She and Raynor have been living on a planet that they have to themselves, and now she accepts a mission to recruit Stukov.

The first part would end with the UED retreating from the Koprulu sector following a battle above Korhal. Valerian, Jorgensen and Sakai decide that the only way to make sure that this doesn't happen again is to send forces to Earth.

There could be a significant moment where the terrans emerge from warp space and see their ancestral home for the first time. The following missions would take place on Earth. Its ruling council ultimately offers terms of surrender. I'd end the game with Valerian signing a peace treaty and shaking hands with members of the UED Council.
