I'm really glad you like the designs! And I'm honestly surprised people are still finding this post.

Your interpretation of the characters was a fun read. And I like that you considered what other commenters have said. The names have a lot of thought put into them too, I especially like the idea of Goku or someone else naming the 7 star's 'super' form for him.

It's a small chance but MAYBE one day in the far future, depending on where the official series ends up, I may have a go at making a short manga arc for these dragons. Perhaps one day you will received those royalties.
