Jubeat emblem graphics?

Jubeat has these emblems that you could assemble in different ways according to preference.
They're composed of different graphics and can be merged together, and are very much customizable.

I'd love to acquire these said graphics and would very much appreciate any help that anyone can provide

I still have some questions, though:
- Are the said graphics in the game's files or are they at the game's website?
- Are they customizable just like DJMAX's DJ Plates and Icons?

Here are some examples (Bonus if they're transparent and in png format):
