Should Treyarch make a free zombie map to promote themselves?

So, I've been thinking... and it is no doubt that Treyarch has made alot of people angry. They have had a few wrongdoings such as, in my opinion, adding the director in Call of the Dead. If you are a die hard fan of zombies, you might like this idea/ideas. Knowing that one of Treyarch's best traits is listening to their community, I propose a new zombie map placed in possibly cod 3, waw, or black ops(preferably not). I think that this map should be free as a gift to us and themselves. If we have many supporting this, it is MORE than possible that Treyarch will act. I plan to post youtube videos about this topic of free maps of the people. This could also help Treyarch by giving them programing experiance and enhancing their reputation as a designer. You guys really need to step it up truthfully. You rep took a nose dive to the floor with all of the mistakes in black ops. So, to the topic of Cod 3 zombies. I can see it being extremely fun and compelling plenty of people to buy the game if they do not own it and go back to the multiplayer, which is about 99% dead. It IS a Treyarch game, but I do not know about compatability or how many people will make use of it. So, it might be better off in waw. I remind you, if we have enough supporters of a new zombie map like this, it could be made! Tell me any ideas about ^^^ and ideas for a new zombie map. PEACE.
