Just playing around. None of these are based on any particular aircraft, although there is some influence from a few unbuilt experimental aircraft designs.
It’s also some indirect ideating for the aerosaurs when they “evolve” into what is essentially their own species. Bottom one is the most plausible in terms of that story - I probably will tweak it but I love the idea of just giant flying shape-shifty oblique wings.
I love this kinda stuff!
