Raid Captains Banner Use

Banners so far are used to gain some extra loot at the end of the levels. I suggest that instead of this more variants of banner should be implemented as well as a Villager or Villagers (Shepherd and Mason) who exchange banners with furniture or decorations for the camp. Speaking of the type of banners, it will depend of the level they were aquiered and the difficulty of that same level (each biome would have arround 2-3 types of banners). The items would be purely cosmetic or maybe they could provide some mini-games inside the camp. As explanation to this, whenever you bring banners the villagers feel safer in the base, enough to add fourniture. This would add a layer of personalisation on the place and I think it would be amazing!!
