1-3-9-17 stellated hexany
A 17-odd-limit stellated Hexany. This creates a scale of 1 17/16 9/8 153/128 3/2 51/32 27/16 459/256 2/1, with steps of 17/16 18/17 17/16 64/51 17/16 18/17 17/16 512/459. This only adds two notes to the base hexany, which do not reduce the size of the largest step, but do increase the number of perfect fifths available to 6 while not adding any steps too small to be melodically useful, making this highly usable but not xenharmonic at all, as it is still essentially a subset of 12edo.
