My Alternator Prowl (finally)

I'm finally getting around to making my Alt Prowl and Bluestreak to go next to my unaltered Alt Smokescreen. Heres the thing, I want them to all look different, but all look related. They were the fairlady brothers. So Prowl doesn't have a tailfin, he's going to have a pushbar, a light bar, a spotlight, and be made mostly of ricochet parts (exept for smokescreen legs and sholders so they're flat).
Now comes the hard part, the head. On the one hand, I absolutely love the head they put on Silverstreak/Ricochet. I've already started altering it by carving/graving into the center of the crest and adding a couple line detailes on the points. I am going to be carving/graving details into the sides of the helmut by the cheeks aswell. If it still looks like Bluestreaks though, maybe I should chop off the side vents and add smaller ear covers (even though I LOVE those side vents)

Then I had a completely different idea, use the decepticharger head/repro. Heres a digibash of it with the crest from the hasbro prowl release, and ear shapes/mohawk added. It looks cool, but is it prowl? Is it related enough to the other two? Do I need to thicken the nose a little so its closer to the brothers? Or should it be my bluestreak head and keep the ricochet head for prowl?
