We can't strive for airsoft to be classified in any firearms category, it would mean they are perceived as firearms (which are legal) instead of toys (which they are). You can get similar toys to airsoft at any kids store, they won't shoot little plastic harmless pellets though, but they look the same.
Don't see why anyone would now consider licensing them in any firearms class, as they do not fit in any, as there is no real use for an airsoft gun except to play with it in your backyard or simulate skirmish. Either one of those is not deadly and never will be. They are toys, simple.
Since the creation of guns, children have played with toy guns. Cowboys and Indians. Pow pow pow
Let's not try to change that, instead reclaim our rights to own these bloody toys because they're the same as any other toy gun you'll find at toys R us, anybody can paint that and it is just as deadly as an airsoft gun.
