Hey all! I recently caved and bought HftD Tomahawk. Even though I love its transformation, posability and the freedom to customize its robot-mode (without actually having to modify it), I am just not liking the head-sculpt... As a result, I decided I want to see if I can replace with a better one. I have noticed that some people posted pictures of their figure with alternative head sculpts (e.g. Landmine, Wreckage). Considering these are all Deluxe-sized toys, I assume they all have similar-sized ball joints for their neck. But what about other sizes? For example, I have been looking at replacing its head with that of either Crankstart (Scout) or the "gestalt" head of Smolder (P.C.C.). Will these heads be too small to fit on a Deluxe-sized toy, or will they fit? I still want to be able to transform the figure back and fort. Thanks for any help anyone can give me!
