[ASOIAF/GAMEOFTHRONES] What would have happened if Robert Baratheon had named his brother Stannis hand of the king instead of Ned Stark?

Stannis would've discovered the truth and he would've acted more effectively. He would not make the same mistakes as Ned, because Stannis is mostly about law and order, not honor. He would most certainly not confront Cersei with this knowledge before telling those who need to know. Even if he thought Robert would have the children killed, he still would've informed him immediately upon finding the truth. Because it isn't about the right thing to do, it's about what's *just*. 

Stannis would find out, tell his brother, and likely crush any chance of Lannister influence of the throne. With no illegitimate heir taking the throne, a war likely would not start even if Robert was still killed. Cersei may not survive long enough to kill him depending on how early Stannis discovered the truth.
