Wall-to-wall Kormorans? Flying over the North Sea or the Baltic from airfields in Northern Germany, external fuel shouldn't be necessary. Six Kormorans would look awesome! Though four plus a Tornado's ECM and chaff pods would also be great.
Ah. Now that's a good point. When I see my girlfriend at Christmas I'll see if I have anything that fits the bill as all my spares boxes were left at her place...I'm not sure if I have anything but I shall hunt!
If you have Taurus cruise missiles and Iris-T air-to-air missiles in your spares box, then maybe you can whiff it into a modernized variant.
Say the Marinefleiger kept the fast jet role and their A-7 fleet got a life extending modernization package:
Glass cockpit (partial at least)
Weapon stations 4 and 5 rewired to take Iris-T missiles, but remain Sidewinder capable.
Weapon stations 2,3,6 and 7 rewired to take Taurus cruise missiles. Stations 2 and 6 maintain ability to take refueling pod.
Weapon stations 1 and 8 rewired for BOZ countermeasures pods.
