sheet

I have a bread recipe that calls for 30 minutes at 425ºF on a cookie sheet. I've prepared this recipe a half dozen times and it always turns out great. It's not broken, but I'd like to fix it. :) I have a 1/2" pizza stone. Would baking on the stone yield a better finished result? If I go the baking stone route, would I tweak temps or baking times?

Thanks,
