Yes, it would be great!! It is much better way to this result. It would
be "randomization" of sound with possibility of exact controlling thru
MIDI controller. But it is not necessary to bind only with Velocity
controller...

I dont know how many, but my second synth - Kawai K-1 has similar
possibility. Attack time can depend on velocity and attack+decay time
can depend on key position as well (e.g. basses have faster attack than
high tones have). I can make a sample, how it sounds. I will try to do
it with some Poly-800-like sound.
