...I'm not familiar with those pedals, and I've never had the disposable cash to buy a Rene Herse crank set. But given your description, I too, would leave the pedals alone in place if the pedal axles are at straight right angles to the crank arms. But to put your mind at more ease, if there is some mysterious damage that has occurred because of this incident, your cranks are not ruined. There's a simple solution using special boring and rethreading tool, that you use to install a threaded insert (on each side, R + L), and that fixes them right back up. The tool and six sets of inserts is far cheaper than the original price of your crank. Some local shops have them, but not all of them.
If you have an issue later on, and you can't either buy the tool and threadserts or can't find one locally, let me know. But the whole back and forth shipping will cost way more than just finding someone local to do it.
