Taking advantage of tempering out 3125:3072, 225:224, 100:99, and probably some more commas that don't come to mind, using 41 equal temperament.

Could you give the scale explicitly? I'm not getting anything useful by googling "homalon".

"Diatonon homalon" is just Greek for "equable diatonic". In 41edo an equable diatonic tetrachord is 5 6 6 or 6 6 5, and an enharmonic tetrachord is 2 2 13 or 13 2 2. Right, Cameron? Not sure how they're combined into an overall scale here.

Yes, I used 5 6 6 and 2 2 13 degrees of 41-et for the equable and enharmonic tetrachords. There isn't really a "scale" per se, but a system of tetrachords. Largely it's simply the two kinds of tetrachords within two conjunct fourths, i.e. equable diatonic and enharmonic mixolydian. So the principal scales would be

12/11
6/5
4/3
16/11
8/5
16/9

and

32/31
16/15
4/3
128/93
64/45
16/9

The voices stick to these limited ranges, but they're set in different octaves, which works together to make something very un-ancient, which would scan as continual modulation in ancient terms, were ancient ears to get past the fact that in their terms it is 2-4 different pieces playing at the same time.

I usually do this kind of thing without tempering, but it is not a question of which is "better", the process and results are just different.
