You could probably also expand your existing typhon board using a few parts following the StormX controller model. It is I2C based and allows up to 16 pwm channels, plus all sorts of other possibilities with programing the spare pins.

I will look that up and see what I can do with that. My thoughts was I would most likely run out of program memory before I got what I wanted.
I still have a homemade I2C shield for my Typhon that allowed me to use all 6 PWM pins. I ran my 20x4 LCD off it with temp. My problem with that was if I enabled all 6 channels the lcd would flicker. If I just did five led channels then it was stable. I ended up going back to the original. One extra channel wasn't enough to make it worth my while.
