Its funny that everyone flies the Taiidan except the GMG... I do not hold to the 'friendly factions ships are ok' philosophy of ship choice even though everyone else does but that is beside the point.
I believe the simplest way to making any new model look like it belongs to a particular faction is in the skinning. Legeonation here has a very distinctive design that seems to show in all of his ships. If his previous model was given to the GMG this new bomber would need a very different skin than the Stinger to set it apart.
If you make it a Liberty bomber it needs the light grey paneled color and the Star/flag emblem on the side or fin. If you make it a BHG bomber it needs a darker grey paneled skin. If you make it bretonian then it needs to be Tan and rust. Kusari would be grey and deep maroon (but I agree this would not pass for a Kusari ship even with an appropriate skin job.)
