Hey guys, I was given a PSE Lightning Flite II (made around 1995-6, I think) from my uncle. It was his first bow, and it is now my first bow.

The plan right now is for me and my wife to practice for next year's bow season, and there's a public outdoor archery range not far away from where my wife and I live in Maryland/DC.
The only problem is, the draw length is so large for her, she cannot possibly look down the peep sight. Can she safely learn how to shoot, instinctively, as though it were a traditional bow?
I don't need anyone to tell me this is in no way ideal and we're better off getting her a new bow---I get it. But we're graduate students right now and frankly for financial reasons a new bow purchase is unlikely before next year's Black Friday season. The main thing I want to make sure of is that there is no risk of injury, and that an anchor point at the jaw is okay for shooting a compound with a release.
