=== 8-note scales as modified 12edo scales ===
As stated many times, octatonic scales in 13edo are heptatonic scales in 12edo with one extra small step. Key: You have a choice over where to put the new small step!
 
You can also view oneirotonic modes as scales made of two shrunken 12edo tetrachords, each spanning a minor fourth, and one trichord spanning a minor third. This will let you 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:
