"[Idea] Unown Raids?"

#PokemonGO: Imagine this, an Unown raid appears in your local area, you and your fellow trainers team up to battle it, however, you are not fighting a single unown, you are fighting a swarm of them, first seen in the Pokemon 3 movie, http://ift.tt/2yfcKZo After defeating the swarm of Unown, you and your fellow trainers have the opportunity to catch an individual Unown, and no two trainers will be able to catch the same Unown letter, meaning that every Unown letter will be unique to trainer in that raid.(As in, If me and 5 other trainers can defeat the swarm, I have the chance to catch "H" per say, and no other trainer will be able to catch that letter in that raid.)Ideas? Comments?EDIT: The idea is that these Raids WOULD NOT be EX raids, these would simply be for example a .1% chance of raid spawns, and the idea behind this is that I have noticed that more frequently, Unown have spawned in the USA, Europe, and Japan, and well, truthfully, the rest of the world it in a "good luck" state with trying to find them, I am in 5 largs groups for my city, containg around 300 people each, and ever since Unown have dropped, there has never been an Unown seen in my city, this is a similar sight for many players around the globe. If Unown were to be called region exclusives for these places, I would be okay with it, however, they are supposed to be Pokemon that can spawn worldwide, which, they don't, I could simply say "increase the spawnrate world wide" however, That would kill the rarity, having Unown Raids IF DONE RIGHT (Hint hint, Niantic) could be fun for players, rare enough to not kill the Unown rairity, and actually level the playing field for Unown hunters worldwide. via /r/pokemongo http://ift.tt/2m1qSnL
