What about a module preset option that would allow us to use the AGM-88 and AN/ALQ-184 Long if so desired? Servers can already restrict certain weapons, so 'retro' servers can still restrict to the Shrike. The HARM firing process would also be a compromise, basically you'd be firing a Shrike model that looks and performs as close as possible to the AGM-88 in speed, range and tracking ability.
I call it the "F-faux G"
At a certain point we're going to have to do things like this if we ever want to see F-4G's, EA-6B's or other heavily classified airframes in DCS and I'm okay with that.
