(REQ) More FedSig Arjent Vehicles

Hey guys, I was wondering why there is a certain lack of police vehicles with the fedsig arjent lightbar. With all the textures that replicate both LAPD and LASD liveries, I'm surprised that there are a few models with their proper lightbars to match. I know there is one CVPI that has the lightbar, but it has this incredibly glossy back that ruins the whole model for me. Also, I've been dying to see it on the Charger and the Taurus models.

If no one else is willing to doing this, I completely understand. I don't have much experience when it comes to 3D modeling, but I am willing to learn if anyone can point me to the right direction.
