Seems easy enough to make. With all the hype over Susanoo, I figure he is a good target for a custom or even a next target for 3rd party Bludgeon (whenever that would come).

Seems like it would be easy enough to make this a viable transformation.

(head swing backward into chest that swings upward, chest collapse inwards slightly?, arms swing back and rotate up to expose arm shield upwards, whole lower torso fold back, rotate wast, legs double bend fold inward, treads/plate rotate around to cover arms on side)
...something like that

I would love see this. (Unfortunately, I have no experience with heavy/scratch customs)
Any thoughts?
