To spin the wheel faster, you would need to increase stepper current if possible.
Or adding some kind of acceleration control would help.
Don't know, if your hardware offers such options?
Both would be possible with an arduino and a suitable driver.
Also slowing down and stop randomly would be easy to program.

edit: The k179 driver has a step-generator chip. Remove it and use an arduino to generate the steps with acceleration/decelaration and random stop. DONE
