How do I make all Players a Model?

I want to know how you can make a Player a Model, basically how it is in "The Stalker".

I recently finished this project. I will not fully explain the script, but it involves creating a new model when a player spawns, naming the model what you want, transferring all the parts and scripts to that model, then setting the character to the model.

Something like:

local Mdl  = Instance.new("Model", Workspace)
Mdl.Name = "Players"
game.Players.PlayerAdded:connect(function(player)
player.Character.Parent = Mdl
end)
