The problem is this simply isn't how pen works, each pen down isn't creating a clone where each line or dot is a separate entity, it simply draws to the stage and forgets about it.

It's a nice idea but I don't think this fits into pen, or indeed how pen work in any way, it would be a whole new pen type extension that works differently.
