Illager Banners in Woodland Mansions

With the new 1.14 update coming around, banners named "Illager Banners" now generate in the world on the heads of illagers who are the illager captains and hang from the pillager outposts. Considering that the banner is for all illagers and not just pillagers due to its name, design, and the fact that it can spawn on vindicators and evokers, it would be a nice--and appropriate--touch of detail for them to generate in some rooms of the wooldand mansions and around the entrance to it.
