Is it possible to make just 1 Player's Character not Auto-Load?

I made a script that reassigns someone's Character property of their Player Instance to a different model and it works, But... After you walk around as that newly assigned Character for about 3 seconds your Player realized that it's not in the right Character and reloads me. Is there anyway to make it not do that? I know you can make the CharacterAutoLoads property false in Players but I only want to prevent auto loads just for me because I'm using the script in Script Builder. I'm not asking for a script, I'm asking for an idea of what I could do to prevent this issue.

Break down: I made a model, put a Head and a Torso part inside, welded the Torso to the Head, put a humanoid inside the model, set my Player's Character property to the Model (Makes your Character Model that model) Example: Player.Character = workspace.Model, then after 3 seconds it realized that it was the wrong character and attempted to fix it by reloading my character.

[Basically I'm trying to make a Psuedo Character]

Just turn off auto load and load characters for players who aren't player1.

noload = {"Player1"} --Add more people.

game:GetService("Players").CharacterAutoLoads = false

game:GetService("Players").PlayerAdded:connect(function(player)
	player.CharacterAdded:connect(function(char)
		char.Humanoid.Died:connect(function()
				for _,plyr in pairs(noload) do
					if not player.Name == plyr then --If the player is NOT player1
						wait(5) --5 seconds before respawn
						player:LoadCharacter()
					end
				end
			end
		end)
		--Add your morph script thing here.
	end)
	player:LoadCharacter()
end)

If this isn't what you want tell me what you want. I couldn't understand your explanation.
