You can't make a silk purse out of a pig's ear - this is how the original wallers built the wall and it stood the test of time.
From the picture below my repair seen from side on doesn't appear very neat. However most of the stones were put length in, where appropriate and there were a number of through stones - no new stone was used in this repair and the rather straggly tops matched the existing wall as can be seen from the second photograph.

But it matches the rest of the wall in style!!
