Suggestion: Add the illusioner to the woodland mansion

In the 1.14 update, Evokers and Vindicates, the two mobs once exclusive to the Woodland Mansion, were given the ability to spawn in raids. This removes one of the only reasons to visit Woodland Mansions, as totems of undying can now be collected in raids. The woodland mansion is one of the rarest structures in the game, so players should have a good incentive to visit the woodland mansion. So, the Illusioner, which is already in the game, but goes unused, could be allowed to spawn in woodland mansions, with it being a mini boss. One reason why Illusioners would not be good in raids was that their abilities would cause the raid to quickly become overwhelming, but this issue could be fixed if they spawned in woodland mansions, as they could have an entire room in the woodland mansion (I suggest the room that looks like a boxing ring) dedicated to the Illusioner, with only it spawning in that room.
