I'm going to disagree. Diacetyl reduction may happen slowly after cold crashing, but may not. All of that alcohol is going to dramatically lower your chances of success. Impatience rarely does a beer good.
This would have been a perfect opportunity for you to NOT be impatient, since you aren't even going to be around while it's sitting cold. If you need beer sooner, brew more frequently or hit up the liquor store.
would suggest if you come back and notice more diacetyl than you can stand, make a 1L starter of ale yeast and pitch into it 18hr later at 68° along with a few ounces of corn sugar, leave it for five or ten days (relieving pressure a couple of times daily if it's kegged) and hope it cleans up.
If you're running low on beer, an eight-hour double brew day will do wonders for the long run. ;-)
