Yes, that seems like a good plan and I have already tried to make it. Decal arrived few weeks later from abroad but the result was not satisfactory. Some letters were not proporcionally correct in the internet and some words were not wavy as should according to original 70's logo. So I decided to make it myself.
I +/- know how to make it. I already have a blank A4 page of special decal paper. I just need logo and some copy center with color laser printer....
Anyway, if you know about some reliable source of decals, please, let me know and I can try.
