The trouble with tuning this in hemiwuerschmidt is that you may as
well detemper it to 7-limit JI, in which case valentine (15&31) or
myna (27&31) actually get you somewhere. :(

Here's the detempered version, which doesn't even manage to be
epimorphic, though I am sure it must have tried.

36/35-21/20-35/32-6/5-5/4-21/16-48/35-3/2-49/32-12/7-7/4-9/5-2

It's a bit irregular, but it does have a nice collection of chords.
