Yeah, that would be fine. Just make sure they understand they can't trade a copy (you can decide if they get a copy for the help). Also, if you don't get any back make sure you know who took it so that I can report them later on. Also, I wouldn't ask to get every single one cloned all at once as that'd be overwhelming for a lot of people. It'll be a few days before I can get them back, so you've got time.
