If you still want to straighten your bats here are a few ideas. But don't blame me if anything goes wrong!
First pour some boiling water in a small mug about half way full. Hold the top end and dip the bent end into the boiling water. Leave it in for a little while and take it out to see if it more pliable where you can carefully straighten it out. You may have to "dip" a few times.
Second way is to heat it with a hair dryer. Again when it gets heated enough you should be able to return it to the desired shape.
Good Luck. Let us know how you make out if you decide to give it a go.
