Yes, it will work as a loaf. But it may not work as a boule as the dough is made to be a softer dough/bread.
To make the rolls as a loaf they may run into sizing issues as this was developed to be 12 rolls.

It would most likely come out to be 1 large loaf or 2 medium-small loaves. The baking time will change as well you’re looking at about 40 minutes instead of the 25 minutes that the recipe recommends. I hope this helps!
