YES PLEASE!!! but arent heads like chests/entities which dissaper? And also i suggest that it does not bring blocks for the craft so that even if you have max sized tanks, ships whatever you want. You can place funny decorative stuff like eyes, a hat and more. Also for stuff that has cannons make it so that it ignores it. If someone would abuse this by like covering the whole surrounding cannon it would turn into an illeagal design.
