Cloning Decals to all sides of a part?

So I have this here that runs in the command bar which replaces a torso mesh (now deprecated) into a block and two wedges. I run this code in the command bar. The script works fine by itself but I need decals to be applied on all sides on the new block and wedges because the game cannot work well without them. How do I link a decal to it and apply it to all sides of all newly created parts?

local properties = {
    "Size","CFrame","Color","Material","Anchored","Locked","CanCollide",
    "Transparency","Reflectance","Archivable","CollisionGroupId",
    "CustomPhysicalProperties","TopSurface","BottomSurface","LeftSurface",
    "RightSurface","FrontSurface","BackSurface"
}
function copyApperance(part1, part2)
    for _,property in pairs(properties) do
        part2[property] = part1[property]
    end
end

function convertTorsoMeshToPart(torso)
    local middle = Instance.new("Part")
    local wedge1,wedge2 = Instance.new("WedgePart"), Instance.new("WedgePart")
    copyApperance(torso, middle)
    copyApperance(torso, wedge1)
    copyApperance(torso, wedge2)

    local middleWidth = torso.Size.X - torso.Size.Z*0.6
    middle.CFrame = torso.CFrame
    middle.Size = Vector3.new(torso.Size.X - torso.Size.Z*0.6, torso.Size.Y, torso.Size.Z)
    wedge1.Size = Vector3.new(torso.Size.Z,torso.Size.Y,torso.Size.Z*0.3)
    wedge1.CFrame = torso.CFrame * CFrame.Angles(0,math.pi/2,0) * CFrame.new(0,0,-(middle.Size.X/2+wedge1.Size.Z/2))
    wedge2.Size = Vector3.new(torso.Size.Z,torso.Size.Y,torso.Size.Z*0.3)
    wedge2.CFrame = torso.CFrame * CFrame.Angles(0,-math.pi/2,0) * CFrame.new(0,0,-(middle.Size.X/2+wedge2.Size.Z/2))
    middle.Parent = torso.Parent
    wedge1.Parent = torso.Parent
    wedge2.Parent = torso.Parent

    torso:Destroy()
end

print("Starting")
for _,v in pairs(game:GetDescendants()) do
    pcall(function()
        if v:IsA("SpecialMesh") and v.MeshType == Enum.MeshType.Torso then
            convertTorsoMeshToPart(v.Parent)
        end
    end)
end
print("Done")
