So, would a Harrier GR.3B or Sea Harrier FRS.1A (basically a GR.3 with the usable upgrades of the AV-8C and a Sea Harrier FRS.1 similarly modified - but with radar upgrades that don't change the profile) in RAuxAF and RNVR FAA markings, respectively, work as current aircraft?
Or a Super Sabre re-engine with a dry F110 and with the four 20mm cannon replaced by a single M61? Possibly re-wired for targeting pods on a hardpoint?
