Need Help - Overnight Cook or Precook and Reheat?

Need some help. I'm having a party this upcoming weekend right after church on Sunday. I plan on cooking a whole brisket and some pork butts. I'm cooking on a 22" WSM and I also have a stoker. The WSM adapter should be here any day so I haven't used it yet on my WSM. My question is if I should attempt an overnight cook, wrap the food in the morning and hold for a few hours until after church. Or just cook everything the day before and reheat on Sunday. I'll be at church probably from 8:45-11:45am. Plan on eating lunch around 12:30. Any advice would be much appreciated.

I have a couple coolers I can use. No Cambros unfortunately. Any suggestions on times as far as starting the night before and trying to finish in the AM? Not really feeling like getting up in the middle of the night to check on anything. Lol. That's why I'm debating the over night cook or not.
