this looked good at first glance,  but then looked bad when I tried

BarLabels -> {Experimental`Rotated["alpha beta", \[Pi]/2],
   Experimental`Rotated["b", Pi/2], "c"}]

here, instead of aligning the "top" of the boxes,  it aligned the 
centers.   

this is close, but in my opinion not as nice as having the tops aligned.

Still think that they fundamentally need to address the ticks problem 
and allow for graphics objects.
