Commander familiars

I was wondering if it's desirable, from a promotional point of view, and possible, from a technical one, to add small cosmetic flying units that accompany the ACU during the game. Here's a visual reference from a game called airmech that used such cosmetics to reward tournament winners, accomplished ladder players and other kinds of achievements and contributions. the transformer airplanes are the commander equivalent, and some of them are followed around by floating medals, trophies, angels, locomotives etc.
