Just  bake it  for lod02  with  flat  cylinder on the top and split  sides/hard edges  or just paint some gradient  stripes manually ,    then  extrude the profile for Lod01  and project vertex normals to be in same direction.  

0r  bake bevel (rounded edges) shader   and mix it with current result if you want to keep that front looking cyinders
