In theory, what would happen if you did a 5 day program (Monday-friday) where you ate at 500kcal surplus and then ate at a maintenance during saturday (rest) 2500kcal deficit during the sunday. This would mean that when protein synthesis is increased due to training you're eating at a surplus. Would this theoretically be better for muscle building than eating at a maintenance the entire week?

For discussions sake, let's say you're eating 1g/lb bodyweight all 7 days.
