Stellaris Mod: No leaders government Thread

I decided to port one of my favorite factions from Endless Space, the Harmony, into Stellaris. One of the Harmony's defining features is that they have no leaders. That means no admirals, no scientists and no rulers.

Initially, I would release this as a stand-alone to let other modders develop whatever faction they wanted without leaders. Afterwards, I would make a mod that has a no-leaders government with specific bonuses.

This is how I was thinking of approaching the development:

1. Make a government type called "No Leaders."

2. Have this trait force the starting leader to be immortal and gain the Arrested Development leader trait, which means they can't get experience.

3. Lower the leader cap to 1.

I don't have any experience modding Stellaris, so any help from someone who does have experience would be appreciated.

Thoughts on this idea?
