This concept has been discussed before. There is such a variation between shallow and deep scalloping that it would be hard to provide what people were after, and there are wouldn’t be enough demand for Adam to have the stock. The belief is the factory(ies) wouldn’t be able to do this consistently, and may not even fully understand what the requirement is. In the end it would probably be cheaper for you to by a spare neck off Adam and scallop it yourself than get the factory to custom make one, and then get it wrong.
