I'm not very kin to implement every possible options for every possible cases. If you need customization beyond what the current "legend" class provide, I recommend you to use proxy artists.
http://matplotlib.sourceforge.net/users/legend_guide.html#using-proxy-artist I personally think that the drawing of the legend handle should be delegated to the associated artist (but fall back to the default behavior when not provided).
