If I'm honest I think that they'd look better if they were dressed up like the AP-2 conversions rather than what appears to be bare metal. I'd also ponder about maybe using the waist gun positions for either infrared searchlights or maybe even fixed waist guns a la AC-47s. Finally I imagine you could also get away with slinging 7 round FFAR pods where the HVARs would have once resided under the wings.
Blackbuck,
The A-25K's are not bare metal, but aircraft gray and white, not bare metal, lol. The IR is in the Turret in the nose. There would be the FFAR's mounted on the wings, but I wanted to keep them clean as I can't mount them and make it look correct. I do not know what Librarian has planned for the waist gunner positions, but both your ideas sound feasible. The belly gun area is probably an IR camera for Aftermath/Result photos. I will be doing a SEA scheme as well with the A-25K.
