Have you tried using the inner shape as the third bit (skinny line or blob of paint)?
you mean something like this:
short/long 01101101101000101101101100111101111101101101111100101000111000101101111101111101111100111001101101101101101000101101111100101000111100101100111001101100

it is a possibility, in some cases the blobs (slim/fat) look like there were corrected.
It is extremely interesting. Maybe even a breakthrough post, for me. If you divide it in groups of 6 (exactly how alphabetcanary did for lengths earlier) you'll notice that the same patterns reoccure all over again:
Look:

I am not sure what to do with that (yet, I hope), just sharing what I noticed
