How could you make a model and clone it to the player and make the player the model?

For example, I put the model I made in Replicated Storage and I clone it and parent it to the player. This is what I thought of but the player does not become the model. I even tried to clone hair to a player without hair and it just puts the hair in the player but it is not on the player. Here is the script.

Player = game.Players.LocalPlayer
function MB1D()
local Morph = game.ReplicatedStorage.Natsu:clone()
Morph.Parent = Player.Character
end
script.Parent.MouseButton1Down:connect(MB1D)

Keep in mind I want to make the player the model I made.
