How do I replace a StarterCharacter with a different StarterCharacter if a gamepass is purchased?

I'm trying to make a chair simulator game where you are a chair, and if you buy a gamepass, it will turn only you into a table. I'm finding some trouble getting the chair turned into a table. I have put a folder with the StarterCharacter of the table in ReplicatedStorage, and I put a script in ServerScriptService that has the following line of code in it:

local starterplayer = game.StarterPlayer
local Avatar = game:GetService("ReplicatedStorage"):FindFirstChild("Table").StarterCharacter


game.Players.PlayerAdded:Connect(function(player)

    if game:GetService("MarketplaceService"):UserOwnsGamePassAsync(player.UserId, 20094414) then
        local PlayerAvatar = Avatar:Clone()
        game:GetService("StarterPlayer").StarterCharacter:Destroy()
        PlayerAvatar.Name = "StarterCharacter"
        PlayerAvatar.Parent = game:GetService("StarterPlayer")
        wait(0.1)
        player:LoadCharacter() 
    end
end)

I would note also that the GUI button that gives you the gamepass is fine, it's this script is the problem. If I'm wrong, please tell me. Also, there is already a StarterCharacter model in StarterPlayer. This is why I have it destroyed when you get the gamepass, so that you aren't a chair, you are a table. I would extremely appreciate it if this was solved. Thank you!
