Getting the banned back together
Ouch! sounds like a dangerous weekend.
I read somewhere that someone cut the sanke dip tube short, put a sank coupler on top without the gas check valve and fermented, chilled, carbonated and served all out of the same keg. Sounds easy enough but I would be worried that I'd pull trub every pint. You would have to be pretty accurate with your dip tube cutting.
When you chill to serving temps the yeast cake solidifies pretty well. As long as you don't wrestle with the keg too much you'll only get yeast/trub on the first pour, and everything after is crystal clear. No need to cut accurately since every yeast cake is different. I cut ~1/2"-5/8" off of my diptubes, and it works pretty well. I honestly think it would be fine left even longer.
