Besides Valt and Aigas facial design, Aiga really isn't that big of a Valt rip-off. Aiga's personality is vastly different from Valts. Being a rip off isn't always a bad thing, it's just the term "inspired" or "clone" is used instead. You can have a good clone and a bad clone. Fubuki is a good character and he is arguably a Shu clone, and Shu was a fairly decent character, although Fubuki was initially more aggressive (Red Eye not withstanding). Fubuki on his own was a good character.
A bad clone in my opinion is Ranjiro, I don't really care for him, not really because he is a Rantaro clone, though Ranjiro is a clone from another character which I don't really care for, and is just a practice partner also. Ranjiro by himself isn't that strong in my opinion, and I don't just mean his skills, I mean his character isn't that great for me, Ohhhh he had that good moment in Episode 31, he still feels too similar to Rantaro, but Rantaro is also a character I don't really care for.

No I don't plan on doing more yet.
I should probably go back to making fan custom Zero G beyblade concepts again
