I Googled this question and was surprised to find hit results of people doing this with varied success.
I inherited them from my parents a decade or so ago. My old man got kind of senile and he'd go to boil some eggs and forget about them. The water would boil away and the eggs exploded leaving egg all over the kitchen walls. That Revere Ware copper bottom pan IS a tiny bit bowed on the bottom, not as flat as new.
If your pans are Revere with copper bottoms, they are not copper but have a copper wash applied to stainless. The other possibility is Revere Signature pans, which are stainless with a laminated exterior. It is hard to make bowed bottoms flat since they bow when they expand.
I flatten copper pans by using an old bowling ball as an anvil, and apply pressure from above by any means needed. But copper is much softer than stainless. It's worth a try with stainless.
