I find the idea of an AC-5 "Gun Galaxy" highly implausible. Compared to your RL AC-130, a C-5 is huge target, a real gas guzzler, and needs a relatively long, well-maintained conventional runway in order to operate. In a T2K setting these traits were become major weaknesses.

When I was a teenager living in Quito, Ecuador c.1988, American C-130s, C-141s, and C-5s would routinely land at the airport. My kid brother could identify any aircraft, civilian and/or military, coming in to land just by the sound of its engines. It was uncanny and quite impressive. The C-5 was by far the loudest of all them (even louder than the occasional 747 that would visit Quito) and could be heard well earlier too- even I could tell when it was coming. In a war zone, the red force could hear it coming from miles away, giving them time to ready their MANPADs and AAA. In such a hostile environment, a huge, loud, slow-moving AC-5 wouldn't last long.
