Though it’s not APLpy, you could try astropy.visualization.make_lupton_rgb (just added in astropy v1.3):
If you increase the Q parameter, and play with stretch, you might get something that remains astrophysically consistent, while still showing your source of interest. Note that it requires the images be aligned, but you should be able to pass in the results from aplpy’s reprojection.

How do I change the relative intensities of the different bands in order to bring it out more clearly? I guess it's the blue band which needs turning up a little.
