Removing Color (Bayer) Filters?

I'm looking for more information about how the filters were removed. I've seen mention that Iliah has performed or experimented with it but I am unable to find very much at all except for the random forum post on how one would go about doing it. I'm also interested in learning how much light is won back from the color filters. I have a camera that i think would make an interesting donor for an attempt. Thanks for any information in advance.
