In the yellow pages of any city you'll find companies marketing Stained Glass Overlay (plastic pretending to be stained glass) doing exactly what you're doing. They've been doing it for at least 20 years - maybe longer.
My comments are neither generalized nor hostile. They're specific and bemused. For some odd reason you seem to think you have something special and unique to offer but all glass artisans have for a great many years seen a huge variety of different efforts to flog plastic imitation stained glass. You might actually get people to buy your product, but this assuredly isn't the place to find them.
