Home of the Sovereign Protectors

Hello. I'm currently watching TCW Series (yes I know I'm a Little late ).
There in the Eppisode "The Zillo Beast Strikes Back" I saw the Senate Guards in their Ceremonial Outfit for the first time and I like the look of that Armor very much.
My first Investigation at the CRLs did not show any sign in any Detachement of that armor. Would that be a costume that we would accept at the Sovereign Protectors? I only saw that Cpt. Arygus was accepted...

Senate guards are for the rebel legion.
Captain Arygus is the only TCW blue guard for the legion.

These Guards would be the Blue Step Children. It is basically the Clone Armor with a ROTS Senate Guard Helmet with Capelet on it. It does still keep the larger Shoulder As the other Commandos. These would Fall inot Rebel Legion as does Jayfon.

Hmmmm to me it does not really make sense why Captain Arygus is approvalble while the Senate Guards are not. At least the one from Clone Wars.... Are the Senate Commando Clones approvable, too?
