i not know if it's possible. , looking @ gallery (http://matplotlib.org/gallery.html), not seem available.

but maybe plt.xkcd() provides clue on how go about.

here source code of pyplot.py: https://github.com/matplotlib/matplotlib/blob/12e08785fcb0b1a6bce946de689a3f84b67731f7/lib/matplotlib/pyplot.py

calling plt.xkcd() change rcparams , namely 'path.sketch' gives randomness of line. so, similar approach experiment rcparams come brush stroke style...

there bunch of parameters play with. (customizing matplotlib, http://matplotlib.org/users/customizing.html)
