The USSR has done it already. No doubt the USA will have also.

The PLA’s Three-Pronged Approach to Achieving Jointness in Command and Control, by Kevin McCauley, China Brief, Volume: 12 Issue: 6, The Jamestown Foundation, 15 March, 2012:

The PLA is taking a multi-faceted approach to find solutions and this article examines the PLA’s three-pronged approach during 2011:

- professional military education reform to educate and train joint commanders and staff;

- construction of an integrated command, control, computers, communications, intelligence surveillance and reconnaissance (C4ISR) system;

- experimentation and testing concepts and communications systems in joint exercises.

Much more at the link. "Jointness" is something that only the USMC has more or less fully mastered, and at that only by organically incorporating most of those elements (minus the 'Gator Navy, especially) that would otherwise be provided by other Services.
