If you are using a "sorta" inverted L then unsymmetrical ground radials are the 
least of your worries. The unsymmetrical top loading causes more pattern 
distortion than the ground will.  Of course, this could be an advantage if the 
"gain" peak is in an optimum direction.

I've been spending hours lately modeling vertical antennas for 160 and 80 
meters.  With the heights that would be feasible for me (I work alone) to 
install, I think that I've decided that the best use for 50-60' of vertical 
tubing is to support an inverted V.  Or as I've been known to say, over the 
ground we have around here, the worst horizontal antenna you can put up is 
better than the best vertical.
