What if John Sedgwick was given command of the Army of the Potomac? and let us say he does fight at Gettysburg, would we see anything different happen, and perhaps even in other later stages of the war.
Sedgwick was a dependable but not remarkable commander. I frankly don't see him doing as well as Meade at Gettysburg. On the second day, Meade (helped a lot by Hancock) were able to hang on by their fingernails by thinking fast and shuffling brigades around like cards being shuffled by a Las Vegas poker dealer. Could Sedgwick pull that off? Maybe, but I doubt it.
When one thinks of Second Fredericksburg he was not very impressive.
