-1, I don't wanna be a debbie downer but there was a genuine reason 101st & ranked CTs were removed. It causes people to think they can progress outside a battalion, which they cannot.
The whole point of clone is to pursue a battalion and help those strive, I can understand the idea of CT leadership but this has already happened before and it achieved little to nothing. CT leadership has kept people in CT instead of in battalions, it pretty much always does this without fail.
People don't need to join battalions they're free to roam and do what they want but if they wish to progress they need to join one. I doubt this sorta thing would achieve anything really. People are always "mature" enough to join battalions, because the point of battalions is to join them and become disciplined and skilful.
And I don't see how you could help someone "find that battalion that best suits them" as a CT leader, if they wanna know they should just hop around battalions and see what best suits them. Second hand knowledge will never be as good or useful as first hand experience.
Another side note, you can't actually send people back to Kamino, like you can't re-train a CT. How mature they are is how mature they are and the only thing that will change that is proper experience and discipline.
As much as we all want it, you cannot have the best of both worlds. Either settle down as a simple CT PVT or join a battalion to actually progress, there is no in-between.
