More than 4 Dynamics: possible?

I'm trying to create the most realistic kit possible for live shows..the four dynamics per pad is good, but I want it to be even more dynamic with like 10 different velocities per pad, is there anyway I can achieve this?

use simult pads for as many as 16 steps

That sounds good, but how do you do this?
