I've done 2 in the last month on my kettle- one yesterday. The kettle handles cold just fine (probably has a little harder time in wind though). You could also wake up early sat morning and do it, esp if you cook at 300, foil it at 160 or 170 and bought two smaller butts instead of one large one.
Just make sure you don't make the mistake I did and let the food probe touch the foil. Threw my temps way off on one of my cooks.
