1) Like Squadron wars! The 2 commanding officers of squadrons in the MA can declare war on each other. Let the CO's set a number of days, up to 7 max. During the war members of both squads can see other all the time.. or some other indicator, like a text message in the buffer like "your enemy has been spotted near (closest base to opposing squad member)". Could use stats from wars to enhance squadron rankings, like kills on opposing squadrons, deaths to opposing squadrons, etc, etc. Your squadron could only be at war with one squadron at a time. Don't know if there'd be enough return on this idea to make it worth the time to code it though.
2) Squadron Skins! Noseart expanded to a whole new level! Skins have to be historically styled, and approved for use of course. Biggest benefit is to the "dedicated" squadrons, that pick one plane as thier "official squadron ride".
For instance:
Cobra412 put that together for the 412th. This one probably isn't worth the effort to code it, but it's a nice dream =)
We now return you to your regularly scheduled Saturday afternoon beer.
