Diamond framed Marilyn poster idea

I went to the Tate to see the Matisse 'Cut-Outs' exhibition at the weekend which was great. This frame hung sideways gave me an idea. Why don't we make our Marilyn 'I like to feel blonde all over' poster diamond shaped? The dimensions as the logo. And then I can get it framed in a glass box frame as a diamond. It would be a pretty striking piece at the back of the shop. If there is power there perhaps we can put a nice light above it? Although I don't think this is important. I think textures and quality and more important than lighting. If you like the idea I will design the poster as a diamond.
