I was thinking I could bake them without cheese on top and refrigerate them. Then add cheese and warm up when ready to serve. Would this work?
Are you channeling your best self with this comment? (If you're not sure, check out our Code of Conduct.)
It would be best to make this dish one or two days ahead, most recipes I consulted said you could either leave it at the stage just before baking or bake it, allow it to cool, and then refrigerate it.
To get it ready to serve, allow it to reheat to room temperature then, if you're cooking it for the first time, bake it according to the recipe, or, reheat in your oven slowly at a low temp (200-300 degrees)
I'm not a big fan of leaving food in the fridge so many days, especially potatoes and cream which can absorb the smells of other things in your fridge. Instead, I'd assemble, cook, and then freeze (and reheat on the day of).
