=== 8-note scales as modified 12edo scales ===
Oneirotonic modes are scales made of two shrunken 12edo tetrachords, each spanning a minor fourth, and one trichord spanning a minor third. You can also build 13edo "tetrachordal" scales with a similar structure that is not one of the 8 modes, with tetrachord structures similar to 12edo ones. For example:
*[2 2 1] [2 1 2] [1 2] is a kind of Mixolydian
*[2 1 2] [2 2 1] [2 1] is a kind of Dorian. I personally think this sounds better than Ultharian.
*[2 1 2] [2 1] [1 3 1] is a kind of harmonic minor (also obtained by lowering the 7th degree of the Celephaïsian mode)
*[1 3 1] [2 1] [1 2 2] is a kind of Phrygian dominant scale (which also contains 1 3 1 2 2 2 2, a chromatic modification of the Zo-Kalarian mode of the archeotonic scale).
*[1 3 1] [2 1] [2 2 1] another Phrygian dominant
You can also just use two tetrachords each spanning 5\13, which would be identical to 12edo tetrachordalism.
With the sharp fourths/flat fifths, you get stretched 14edo tetrachordalism...
