Take them to a rim shop and have them trued. It has been my experience (yes, I've tried) in the past it will never come out right. Even when I did get it right (or so I thought) it quickly went back out of round. By taking it to a shop, they will use whatever magic is involved and get it straight ... and it'll stay that way.
Even if the tire does hold air (though, being run flats you may not be overly worried ... just joking), you will feel the thump, thump, thump of the flat spot as you are driving down the road. Since you have two bent rims, the thumping is going to be even worse.
