Yes, this is easily doable.  The fond obj command works on any
matplotlib instance, so for example, if you wanted to selectively
change the text properties of the xaxis::

  # see matplotlib.text.Text for information about the settable properties at
  # http://matplotlib.sourceforge.net/doc/html/api/artist_api.html#matplotlib.text.Text
  for t in ax.xaxis.findobj(text.Text):
      t.set_fontstyle('something')
      t.set_fontsize(12)

for the legend you would do the same:::

  leg = ax.get_legend()
  for t in leg.findobj(text.Text):
      # set some properties here

All the text setters just forward the calls onto the FontProperties
object (see matplotlib.font_manager.FontProperties) so   take a look
at this object to see what is available.  Eg, from my previous post,
you can set the fontname explicitly with::

  prop.set_file('somefile.ttf')
