Modes with a flat 5th degree sound weirder and less stable to diatonic ears, but this can be alleviated by treating the flat 5th degree as an 11/8: Mnarian has a 4:9:11 on the tonic, Hlanithian has an 8:11:13 on the tonic, and Sarnathian has the Beloved Extra Special Chord 4:5:11:13 on the tonic.

You can also view oneirotonic as scales made of two 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:
