I'm working on this exact issue with a delivery company currently. The biggest question they have is "would you pay for it?". Would you pay extra to receive a message to advise of delivery time, and would you pay extra to have that delivery delivered at another time or elsewhere?
Whilst missed deliveries are costly they obviously don't feel that is justification enough to develop a better solution.
My own personal opinion is no, I wouldn't pay for this service. However, maybe the costs can be driven down by simplifying the solution. Instead of 'deliver wherever the customer wants,' only present the customer three options: 'Receive at home,' 'Receive at work,' 'Don't deliver, I'm out of town'. This solution perhaps reduces the complexity in customizing delivery location (fewer possibilities), pushes down delivery costs (fewer missed drop-offs), and increases customer satisfaction (receive package with less hassle).
Some of the consumer delivery firms that Amazon use in the UK have started texting the night before (or early on the day) with the option to either delay delivery or to deliver to alternative -- but the alternate delivery address must be in the same postcode (between 1 and ~20 houses) so no re-routing is required.
