I know this is an older post but commenting anyway...I actually use the bottom of my cast iron skillets for pizza all the time.
I leave it,upside down in the oven while I preheat the oven.
I roll out the pizza and make it, slip it onto a peel, and then slide it on to the hot, upside down skillet that's already piping hot :)
Sometimes I put a bit of cornmeal on the bottom of the crust to prevent sticking. Works like a charm!
I use the inside of the pan if I'm doing a deep dish though ;)
