Desire for SWN faction system in D&D?

I was looking for something a lot like the Faction rules in Stars Without Number to plug into my upcoming 5e campaign, but couldn't find it. is that something others would be interested in? If so I'll expand my work to include reskinning all of the units. Otherwise i'll just be reskinning what I need for the 8 or so factions I'll be using. Also, if somebody has already done this, shoot that link over and save me a lot of time.

EDIT: I realized some may have never heard of this. Stars without number is a sci-fi rpg built to benefit a sandbox play style. It has rules to manage the factions competing for resources in any given sector. If this intrigues you, check out Counter/weight, which is a mechnoir podcast that uses the swn faction rules, or Swan Song, a rollplay show where they play SWN with Adam Koebel as GM (there are videos of Adam creating and managing the factions behind the scene).

EDIT 2: Not talking about the factions in forgotten realms. "Factions" refer to groups of people who want a thing and take actions separate from the players to acquire them.
