That is the plan, except assembly the night before.
In fact, each recipe, with the exception of NYT, mentions that. The NYT version had it in the comments.
I am finished with most of the prep, including 2 pounds cubed potatoes, roasted. Interestingly, some say no need to pre-cook store bought hash brown or cubed potatoes. 
Last year it took a little longer than expected to cook through, but I can get up early every few …12 months.
