We should make this happen.
There is a thing called Greenlight that people can vote on a game that is submitted. I'd love to play this game on Steam, and I'm sure it will grab new people in considering some people are turned off by the fact it is a "mobile game" or a "Facebook game."
Just a thought. Have people asked the men in charge of Graal if this is a possibility or if this is something that they would consider? (I don't know who runs Graal anymore... Unixmad?)
