I think the publisher would go along with it. They are going to make more money and don't have to relax the restrictions on their digital license in any way.
As I explained they would not be losing money because nobody is going to buy the book twice under normal pricing. Getting people to pay more for the same book is a good idea.
I don't think the VHS to DVD example is a good one because you don't buy those at the same time and one does not augment the other in the same way an e-license augments a full rights printed purchase.
