People like to experiment with ideas. I have had a few of my own. I really not know a recipe, but, this may be one of those things that not work. You may be able to contact someone like "Interlux" and ask;
yachtpaint.com - the official site of International and Interlux paints (I guess this a good link to start).
If, it worked I assume Paint companies would use the idea. My reasoning is we are seeing more and more EPA intervention over bottom paints. Even the copper based paints are now under the scope. I can understand as anyone with a saltwater aquarium knows, you do not drop copper pennies into the tank.
You can try what you wish and learn first hand, nothing wrong with experimenting. I know some people with wood boats in southern water use a Latex Exterior house paint on the bottom of their boats. Very long story and I have been surprised they not get those worm/parasite things in the wood. But, anyway, that what they do every few years.
Do a Yahoo search; boat paints cayenne pepper
I found this;

The link not work so I remove, in the search you can find. But, the pdf is the same.
