Way back when, a group of VMF's banded together for Tour of Duty (now FSO). They also participated in join operations to some extent in the MA. These were Marine Air Groups (MAG). One of the more notable ones was MAG-33 which consisted of: Jim Bears VMF-111 "Devil Dogs", Redwings VMF-115 "Joes Jokers", Ripsnorts VMF-323 "Death Rattlers", Jebo's VMF-222 "Flying Deuces", Troxels VMFA-212 "Lancers" and ColBecks VMF-214 "Black Sheep".
You may want to consider a same type of alliance, individual squadrons forming a co-operative group.
