You're projecting what you want to see here. Put the heads side by side, they are only the same in the very abstract. Much like Prowl and Optimus Primal, as was just being discussed a few pages back. There are tons of transformers with helmets with a center ridge. Look at Alternators Skids, just as a simple example. Is that Ironhide too? He was never Ironhide. I can see the idea working though, and I understand why you might like it. I think a lot of us wouldn't mind seeing the "Beast Wars as a straight continuation of G1 with Optimus Prime and Megatron" storyline fleshed out someday. Maybe Ironhide as Armordillo would be something to consider.
