Word, and they did just that in the comics. Both Killmonger and M'Baku run their villages, each village being a reflection of their political beliefs.
Most def. Let's all consider the stances in Wakanda, assuming the MCU stick to the comics on that one:
-M'Baku wants to go back to the old ways.
-Killmonger wants Wakanda to go the western route.
Already you have potential conflict with the monarchy. Then within the monarchy itself you have:
-T'Challa, who wants Wakanda to move forward and no longer be as isolationist as it used to be.
-Royal family members (depending on which ones we'll see) who are like
about the outside world, preferring to deal with them only if needed, if at all. Some think T'Challa is going a bit too far.
Add all that to T'Chaka dying the way he did in Cap: Civil War and you have a political mindfield with potential beefs all over the country. T'Challa will not only have to punch people here and there, he'll have to get his politician on and put out the potential fires in the country.
And in the midst of all that, Nakia is sprung for T'Challa like
, Okoye is trying to dead that, Klaw is in the cut ready to make his move, and Ross and his peoples are like
somewhere, wondering how in the hell they even got themselves involved in all this fukkery.
If that's how the movie will be, then we're in for a treat
