Question to Energon Kitbashers...

...I just got Energon Ironhide for $2 on Clearance at K-Mart. I like him, but the whole, exposed head, gigantic red, swivel, cannon thing is bugging the crap outta me.
Has anyone successfully KB'ed this figure? I want the head to disappear in Car mode, and get rid of that ridiculous red eyesore.
If no one's done this yet, any idea how I'd go about doing such a thing?
