I wonder if hspace and wspace in gridspec should take arrays like 
width_ratios and height_ratios. Try axes_grid1 instead.

(though the documentation is not the best)

I think this example does what you want:

M

import matplotlib.pyplot as plt
from mpl_toolkits.axes_grid1 import make_axes_locatable
import numpy as np

clf()
ax = plt.subplot(111)
im = ax.imshow(np.arange(100).reshape((10,10)))

divider = make_axes_locatable(ax)
ax1 = divider.append_axes("right", size="100%", pad=0.0)

im1 = ax1.imshow(np.arange(100).reshape((10,10)).transpose())
cax = divider.append_axes("right", size="5%", pad=0.05)

plt.colorbar(im1, cax=cax)
plt.draw()
