Sloped Minifig Leg 3817b is wrong

[Magnus Forsberg]

I made an experiment to see how difficult it is to adapt an existing pattern with "b" leg geometry to corrected "c" geometry.

I chose this one as it was a good case with front/side/toe pattern.
The most tricky part is the adaptation of front curved subpart, shortened at bottom. Adaptation made using LDPE only.

What tools did you use? 
I remember using "Merge to Nearest Face (Direction)" and "Merge to Nearest Edge" a lot.
