Bones can be vestigial, or so intertwined with how the membrane expands that they aren't being selected against. The presence of legs possibly being inaccurate also does not negate the possibility of the organs being located below the arms and therefore not part of the head.

In fact, your illustration completely ignores the arms. Where do they attach? They need to attach to something solid or they will be torn right off with ease. Your illustration is, by your own logic, completely negated by this problem, and therefore by your own logic you are completely and totally wrong about everything regarding the anatomy of the bird blob.

And primitive bilateralians being aquatic on earth doesn't mean that aliens that are not on earth have to evolve the same way.
