I'm sure plenty of players want to create their own PvP maps, Strikes, or even Raids; one big problem is how it would make sense within the lore. Mercury. There should be a one-time mission/cutscene which unlocks a Mercury zone allowing the [i]simulation[/i] of said activities via manipulation of Vex technologies. I mean, there has to be plenty of space on Mercury to work with. I'm sure the Vex won't miss it, or maybe they will, and we'll have to fight them for it, that'd be interesting. What would you make if you where making a PvP map, Strike, or Raid? Would you make something original, or remake a fan favorite?
