Depending on heat levels, the screen looks like a good option and I actually have one which is nice!You can. But the screens are used under a raw dough and designed to slow the crusts cooking so the pie cooks more evenly. Once the pie is set, you deck the pie, remove it off the screen, and crisp up the bottom on your stone or steel.
Many NY pizzareias use screens as a NY pie takes longer to properly cook. If the deck, stone, is too hot, the bottom will cook before the top does and your pie will taste raw.
The screen acts as an insulator and promotes even cooking.
