Yes, I think if you made some move to make this proprietary and market it, you could make a great deal of money.  Considering that a large moderate quality eye package typically sells for $5-15, putting this kind of power and flexibility in somebody's hands could very easily go for a similar or even somewhat higher price.  Note that common brokerage agreements give the broker 50%, which means $2.50 - $7.50 per unit for you.  I'd give you $20 for this for absolute certain.  

If on the other hand you decided to give it away free, you would be up for sainthood right along side Anton Kisiel.  Matmatic is certainly cool, but this technique has a concrete application in every single human figure render (which is basically all of Poserdom).  

Some kind of dialog interface for basic layout would probably be required but I expect that is the easiest part for you (it sure would be for me).  Coordinates for a variety of figures would be very desirable as well.

Note that nobody has a one-size-fits-all eye kit as far as I'm aware.
