Well, you didn't ask me, but I am appalled that two of you are making huge dinners with no help!

That's how we did it at the truck stop I worked at, back in the 70s, 80s and into the 90s. Basically, customers got leftovers: Four whole turkeys and four bone-in, skin-on turkey breasts would be roasted very early on Wednesday, allowed to cool completely, then were cut into boneless sections and the chunks were placed into hotel pans, wrapped in foil and chilled.

Midmorning Thursday, the foil was removed and the turkey got misted with broth (diluted stock) from a spray bottle. The lid was placed on the pan and the pan was put in the steam table to heat gently until serving time. To prevent it from drying out, the meat wasn't sliced into serving portions until it was ordered.

The bones were turned into stock for the dressing and gravy, which were also prepared in Wednesday. This freed the ovens for baking the pies and biscuits very early Thursday morning.

My brother has done this for the last several years just as you describe, cooking and slicing the day before and reheat in the oven with stock. I had my doubts, but it was moist and delicious. The only thing you miss is the smell of a roasted turkey wafting through the house. But since you won't be having any help with the dinner I say go for it! I too have a family full of brothers and and there is absolutely NO help in the kitchen.

I would do everything else on Wednesday, like stuffing and side dishes but cook my turnkeys on Thursday.

Yes, it works. Have done it for years. Covered, low heat, little stock, you'll be fine. The real safeguard is to have plenty of gravy.
