best way to make morph a player into a rthro character?

im trying to make a morph button that changes a players character into the rthro character without killing them, this is just the test script and when it executes, you teleport to where the original model is and die instanly. any suggestions?

local modle = workspace.RTHROT:GetChildren()

game.Players.PlayerAdded:Connect(function(plr)
	wait(3)
	for i,v in pairs(plr.Character:GetChildren())do
		if v.Name =="Humanoid" then
		else
		v:Destroy()			
		end
	end
		
	for i,v in pairs(modle)do
		if v.Name == "Humanoid" then else
			local clone = v:Clone()
			clone.Parent = plr.Character
		end
	end
	

end)
