Are the MD-80's structurally sound to be converted into cargo freighters and has there ever been interest in such a development? If so, would it not be a logical successor to the widely used but aged fleet of C-9B's in U.S. military inventory?

Structurally there is very little difference between the DC-9 and the MD-80. The fuselage is the same structure with an extra section inserted forward of the wing. The wings are longer on the MD-80.
As far as the US military converting used MD-80s to replace the DC-9 fleet it wouldn't happen. They are buying 737-800s to replace the DC-9 fleet. The US military prefers to buy new aircraft. They would only convert used civil aircraft if no new aircraft fit the requirements. I think the JSTAR aircraft are converted 707.

Actually, a number of the USN C-9Bs were acquired second-hand (in some cases 4th or 5th). Almost all of the ex-airline C-9s were CF airframes similar to the new-build C-9s. The CFs came from Douglas with cargo doors and beefed-up cabin floors.
The cost of those aftermarket modifications to a relatively small number of Mad Dogs (in addition to acquisition and training costs) would be prohibitively expensive. The Navy is getting new custom-built airframes in a package deal which includes training and heavy MX.
