Not my area of expertise, but an article on the 54FS in the AAHS Journal suggests that the F-5s were assigned to it, operating alongside P-38Gs.
To quote, "The squadron began receiving P-38Gs as replacements for the P-38Es that had been lost. The first of several F-5A photo reconnaissance Lightnings arrived 18 March. Prior to their arrival the Eleventh Air Force had depended on its bombers for that capability". It states that three of the squadron's F-5s were based at Amchitka to cover the invasion of Attu in May.
