I need a separate theme for each color, is it possible?

[ksielski]

I have created 3 custom color schemes for my Streamline theme - silver, gold, and platinum, corresponding to membership levels. My membership plug-in let's me load a different theme for each membership level. Is there a way to create 3 'instances' of the Streamline theme, one for each color? Basically, I need Streamline_silver, Streamline_gold, and Streamline_platinum themes as theme choices.

I tried making 3 copies of the streamline theme files and and they showed up in the themes chooser, but they default to the gray Streamline color, and they don't have my image logo.
