This is going to lead to a full on project but for now i wanted to share this. Apparently most or all of the RotF bots can change heads with eachother (the Delux's atleast) so while messing around this morning trying to see which of my figures an Armada Delux Prime head could fit on without wildly using my dremmel at 7 A.M. waking up the wife and surrounding appartments, i got bored and swapped the heads on BumbleBee and Soundwave from the NEST 2 pack - Now I wanna grab another BB and SW for a custom that I have in mind but here are the pics. I feel that the head from each opposing bot looks great on the opposing body (hopefully you understand my meaning). I was, at first, worried that Soundwave's head would prevent if from sitting flush on a surface but i discovered that the fears I had were unfounded as the wheels 1) mask the antenna, and 2) the antenna never reach half way down the wheels. Tranforming was another issue but as you can see, that was also unfounded.
