Improved Custom Faction Creator (March Update)

Okay so this idea was actually inspired by @Torahel's comment 

Maybe an improve custom faction creator could allow it.

"It" being a reference to this thread, which is about hypothetically making some minor factions as major factions. 

So improving the custom faction creator could be:

1. Choosing the image that goes along with your main population (I can't mod/code so I don't even know if this would be possible though)

2. Being able to make a custom faction whose population is one of the minor factions. 

3. Having more freedom when designing the homeworld of your faction. 

4. If Pirate/Minor Faction ships are ever expanded, then being allowed to choose those ships over others. 

(for ground troops, the minor factions ground troop models are already added in game, so I figured it'd be possible to choose those too). 

None of this is a critique against the custom faction creator though, I actually really enjoy it and use it a lot, but I think it can be improved or give more freedom to the players to create factions that aren't just reworked versions of only the major factions. 

Also, I think it's good to note that some of these changes complicate with the Gameplay/Visual Affinity, but honestly I feel as if that needs a change too. It's a bit weird that I have Horatio ground troops fighting for a custom Vodyani with the Gene-Splice affinity.  

Anyway, add any changes you would want in the comments and I'll put them in here with your name and stuff. 

(These are my other ideas)

Cheers !
