I think having separate services is a good idea but I also think that combining the civilian departments (Department of the Army and Department of the Air Force) into a single department might help (similar to the Dept. of the Navy covering both the Navy and the USMC.

They already did in 1947...it's called the Department of Defense.

As pointed out in post #81, sort of / not really - the 3 service departments continue to have separate existences, subject to the control of the Secretary of Defense. So they are not independent and they are not totally on their own but there is real meaning to their being separate departments.
