Tealboy, rather than a bunch of trial and error I would wait until the new stock arrives, the butt stock will be longer and should move the rear of the scope further away from the shooters eye. If your daughter has a full field of view with the barreled action in the new stock leave it as is, if there is a problem take it to a gun smith, it isn't that expensive to have them look at it and give you options. Take it easy this is not an insurmountable or bank breaking situation.
