Swapping Player´s Identity by Using player.GetAll()

[Pythagorion]

Greetings.
Is it possible to swap the Identity/nickname of all living players by using player.GetAll() and if it´s possible how?
If it´s not possible which options do I have?

Thanks in Advance.

"swapping identity" = changing the nicknames of all living players. E.g.:
Player1, Player2, Player3 and Player4 are alive. Now they swap their identities. The Consequence: Player1 is shown as Player4 etc.

2. I know what player.GetAll() does. My idea was that:
[lua]for q, w in pairs(player.GetAll()) do
    if w:Alive() and w:IsValid() then
 (HERE COMES THE "SWAPPING-CODE")
end 
end[/lua]

You could detour or make wrappers for PLAYER:Name/Nick, PLAYER:Team, etc that take into account the player's proxied identity and return the appropriate values.
As a milder example, DarkRP overwrites PLAYER:Name/Nick to return the player's RP name instead of their Steam name.
