Group based world PVP idea!

[Enrei]

Alright, hear me out. Feel free to tell me if this has been proposed already...

I don't want world based PvP, but I do want PvP, and of course, there are those of you who want open world PvP. So how do we make both players happy?
Include a sort of "PvP guild" which will be open for 3 weeks out of the month, with one week of cool down time. Players will register for a team during the cool down time, or just register for the event and receive a team randomly. During the 3 week event time, players of each team(Red and Blu for now) will be encouraged to hunt down and massacre the opponents to get points. Additionally, Red/Blu will be able to accept special leves/quests/NM hunts to boost their points. The winning team will receive some kind of bonus during the cool down week; possibly access to a special dungeon, special quests, unique crafting material, and access to cosmetic-only winner's gear(the "hell yeah we won!" hat)

Well? Thoughts? Again, this would let those in favor of world PvP have their fun, and not disturb anyone else, and you could take a break when needed(at least, untily ou sign up again)

This idea was heavily inspired by Monster Hunter Frontier's(the Japanese Monster Hunter MMO) Hunting Festival event.
