How to add narrative content for our Spartan IVs

Greetings Spartans,
I am reflecting on the limited narrative content for our multiplayer characters (so far we can only see our chosen armor colors outside of menus in free-for-all arena) as compared to past titles which strongly identified the player with their character (Halo Reach and Halo 4: Spartan Ops). I am curious how Halo 5 can utilize similar features to increase its lifespan.

I propose DLC or a smaller, additional game using the same engine (similar to how Bungee created the semi-sequel Halo 3: ODST) that includes a standalone “strong and silent type” narrative for our multiplayer characters with cinematic cutscenes showing our customized Spartan teams/companies. Perhaps the easiest way to package this is an additional season of Spartan Ops sold for $20-$40.

How else can 343i build upon the core game to allow a stronger connection to our multiplayer characters?
