Hardhead vs Skyfall Upgrade?

I’m starting work on my Hardhead vs Skyfall addon parts. Both heads will incorporate the light up eyes feature that the toys have. This is a must for me. Below are concept designs for Skyfall’s new head. Its based off the G2 Skyjack figure, who Skyfall is suppose to be. I’m also thinking of adding a sniper rifle as a new weapon for him, which was suggested by my friend.  For Hardhead, just have a rough vehicle mode for concept for him.  Both photos are from Seibertron.com.

And here is a rough model for Skyfall’s new head.
