Sure, it only needs a slight change in the C code, but I do not want
to have the shasum of a password and prefer the shasum of the entropy,

One question I ask myself:
Aren't you losing entropy when you use the modulo operation
in the "bytes_to_chars" function? I wonder.

Yes.
He'd do better restricting his character set to 64 elements, and then using his entropy 6 bits at a time without any need for the mod. Practical upshot: slightly longer password at no extra cost other than slightly awkward programming as you dance around the bits.
