I think a shorter Civil War more easily won by The Union than in OTL would still have led to emancipation. I think that emancipation would have been a planned emancipation, perhaps done gradually, maybe phased out over a set period of time.
Slavery was an embarassment to The United States in terms of how the rest of the world viewed us.
But more than that, the fact that it had brought us to a Civil War would have told everyone both North and South that this was something we had to really deal with, and the only way to deal with it was to bring the institution of slavery to an end. So I think a shorter war more easily won by The North would still have led to emancipation, but that emancipation would have been handled differently than in OTL.
So slavery was an embarassment. It wouldn't matter once the wayward states were brought back into the fold. It didn't matter before, either. Britain never had the power to threaten America over it, neither did any other nation. The British couldn't even threaten Brazil. At that point in time, sentiments weren't high enough on either side to allow emancipation. The dominant mood was of Free-Soil, and many Northerners were against Abolition.
Its more wishful thinking than anything else to believe that emancipation would come about from a shorter Civil War. Its wishful thinking to believe one could wipe away so much of the blood and unpleasantness and still have the (relatively) bright end. You can't.
You may see a more "conspiratorial" view of the Rebellion, with prominent leaders being executed or exiled and these "traitor's" slaves being freed. But beyond that and maybe a war contraband order, there will be no emancipations. There will be a definite end in the territories, but that is it. Slavery will survive in the South until they rise again to defend slavery, or until it peters out due to economic circumstance.
