Topband: Radials over a stone wall

I shunt feed my tower for topband. I use variable vacuum caps and a vacuum
relay at the base to switch between the low end and the high end of the
band. It seems to work okay. I have 100' buried radials spaced 10' at the
ends from o degrees going clockwise through about 220 degrees. I have a 4'
high stone wall that runs about 20/200 degrees that is about 35' at its
closest point to the tower. So the radials are progressively shorter on the
West side of the tower.  

 

I am making an assumption that going up over the wall will distort any
benefits of extending the radials on the West side? Is that a true
assumption. 

I can't really have the radials go from the tower base up at an angle to
clear the stone wall and continue on. If I am to extend them the radials
would have to go on the ground to the wall then up and over and back down to
the ground.
