1-3-7-15 stellated hexany
The second simplest possible 15-odd-limit stellated Hexany. This creates a scale of 1 315/256 21/16 45/32 3/2 105/64 7/4 15/8 2/1, with steps of 315/256 16/15 15/14 16/15 35/32 16/15 15/14 16/15. This only adds two notes to the base hexany, which do increase the number of perfect fifths available to 4 and reduce the size of the largest step while keeping the smallest ones the same size, but there is still one step that is more than twice the size of all the others and there are no familiar thirds available, which means it remains surprisingly xenharmonic considering its low factors.
