Ideas for spoiler mod wanted

[square-root]

Hi all,

I really like the "center reflector" style of the 996 4S and others, and was wondering if any of you have ideas on how one could create a red reflector in the shape of the 986 spoiler trim piece (the very top of the spoiler).

So here goes: If you were to create a red reflector spoiler trim, how would you go about it?
