I wouldn't be averse to wearing CS95 as my routine daily garb, nor would I complain about a change to the name of my rank. The important issues such as force structure, command and control, etc, probably wouldn't change much anyway. CAOC is CAOC, PJHQ will still be PJHQ with the intentions of putting the right people in the right jobs. An airfield stn cdr on posting would never then be put in charge of a corps of main battle tanks. A colonel will never be put in charge of an airfield operating ISTAR assets, although there would be an element of ground forces stationed at that unit for good reason.
There would be some savings made in terms of personnel management, although JPA is already taking care of that issue anyway. Geting rid of regimental/RAF dress codes will also save money, but when we consider the costs of building and maintaining ships, aircraft and tanks, the savings to be made by "integration for presentation" is negligible at best.
