Hidden/Scrapped characters ?

i'm a huge fan of the jedi from the galactic republic, so i was really surprised when the update with the cantina upgrade came out. I did some test to try to see if they were unique character but sadly they are just doppelganger, EXCEPT for one !
there is :
- Saesee Tin (look like based one Ima gun di)
- Agen Collar (look like based on Luminara Unduli)
- Even Piel : basic grant him stealth and critical chance up/ special an aoe that can ability block opponent. he's slow and seem to be a tank (he take less damage from the others like plo koon) it can sound weird since he can use stealth, but I think it's because they are juste scrapped characters. 

If you want feel free to create an attack set for one/all of them.
