As long as its not required to join in if you dont want to I see no problem with it. The win the war types will flock together regardless. What would be nice is if the mission planner was more attractive. Maybe putting you in the ready shot we saw quite awhile back with all the pilots sitting. Do what AW had. Someone ran the breifing and people would raise their hands to speak.
Have a map that waypoints can be placed and moved around and notes added for all to see. Stuff like that makes it more fun.
