I realize it would require more programming effort and resources than some of the other suggestions in this post, but:

Spreading Triple Draw would be great, as well as dealers choice games.

Implementing a draw engine in the software would also allowed you to spread draw high as well.

Draw high generates decent traffic on Pokerroom and TD a fair amount on UB, especially at the higher limits, so it's most likely a propostion that would prove beneficial for you as well.

Razz would be nice too which I imagine would be much quicker and cheaper to implement as you already have the stud engine in place.

Your ear to the audience is quite incredible I must say, props and thanks for listening.
