How to load character with custom meshes for body parts?

So I'm working on a game where you can choose your character, and the way it works is that when the player selects a character from the menu, it fires a remote event, and multiple scripts check the second parameter of the event, which is the name of the ability (by default, the first parameter is the player), and if the second parameter of the remote event is equal to the name of the ability in the script, the code will run (I have made an example of this below). My issue is that I want to reduce the number of lines of code while also supporting characters with custom mesh body parts and making it more secure to prevent exploiters.

game.ReplicatedStorage.AbilityLoader.OnServerEvent:Connect(function(Player, AbilityName)

    if AbilityName == "Noob39" then
        Player:ClearCharacterAppearance()   


        local Character = Player.Character
        local Ability = game.ServerStorage.Abilities["Noob39"]

        if Character:FindFirstChild('Animate') then
            Character.Animate:Destroy()
        end

        for _, v in pairs(Ability:GetChildren()) do
            if v.Name ~= "SwordGrip" and v.Name ~= "Sword" and v.Name ~= "Band" then
                local Clone = v:Clone()
                Clone.Parent = Character
            end
        end

        for _, v in pairs(Character.Humanoid.Animator:GetPlayingAnimationTracks()) do 
            print(v.Name)
        end

        local RightBand = Ability.Band:Clone()
        RightBand.Parent = Character
        local Weld = Instance.new("Motor6D", Character.RightLowerArm)
        Weld.Part1 = RightBand
        Weld.Part0 = Character.RightLowerArm
        Weld.C1 = CFrame.Angles(0,math.rad(90),0):Inverse()

        local LeftBand = Ability.Band:Clone()
        LeftBand.Parent = Character
        local Weld = Instance.new("Motor6D", Character.LeftLowerArm)
        Weld.Part1 = LeftBand
        Weld.Part0 = Character.LeftLowerArm
        Weld.C1 = CFrame.Angles(0,math.rad(90),0):Inverse()

        local Sword = Ability.Sword:Clone()
        Sword.Parent = Character
        local SwordGrip = Ability.SwordGrip:Clone()
        SwordGrip.Parent = Character
        SwordGrip.Part1 = Sword
        SwordGrip.Part0 = Character.RightHand

        if Character.Head:FindFirstChildOfClass("Decal") then
            Character.Head:FindFirstChildOfClass("Decal"):Destroy()
            local NewFace = Instance.new("Decal", Character.Head)
            NewFace.Texture = "http://www.roblox.com/asset/?id=8260834354"
        end
    end
end)
