1-3-5-7 by 9/7 bihexany
The simplest possible Hexany, offset by the second simplest interval that produces a full 12 note bihexany with no duplicates. This creates a scale of 1 15/14 9/8 7/6 5/4 9/7 35/24 3/2 45/28 5/3 7/4 15/8 2/1, with steps of 15/14 21/20 28/27 15/14 36/35 245/216 36/35 15/14 28/27 21/20 15/14 16/15. Like its source hexany, this is actually less evenly distributed and contains more obviously xenharmonic intervals than the 1-3-5-9 by 7/5 bihexany. However, it can still be mapped to a standard 12 tone keyboard without any note deviating from 12edo by more than 100 cents. 6 of the notes have perfect fifths above them to create stable chords with and all of these are mapped to 7 steps above their roots.
