Should there be another "Legends" game like LoW?

I was thinking, since 2K will be making the WWE games in the near future, should there be another Legends type game like Legends of Wrestlemania and All Stars....but this time the tagline would be WWE vs WCW vs ECW and you would have rosters full of those guys. I never understood how THQ had limitations for the WWE games but with the UFC games they had 80+ characters and 100 CAW slots.

It's a fun idea, but I don't know why WWE or 2K Games would invest their money into some sort of multiple federation game without any actual reason. Besides that, they'd have to pay all the former ECW and WCW folks for their likeness and all that jazz, when they could just let users put their time and effort into doing all the work and sharing it in community creations.

In regards to the UFC having more slots, I haven't a UFC game since the first Undisputed, but I'd imagine each character takes up a lot less space since it's a lot more basic than a wrestler. There are only a limited amount of strikes and subs in comparison to wrestling. Also, the attires are much more simple in MMA.
