The 5-limit temperament tempering out the kleisma, 15625/15552 has in fact been given the name "hanson" by Paul Erlich. The generator is around 317 cents, a slightly sharp minor third. There are MOS of size 11, 15, 19, 34, 53, 87, 140 etc.

Larry Hanson's keyboard design is described here: http://www.anaphoria.com/hanson.PDF More detailed information about the chain of minor thirds scale (specifically an 11-note version of the scale, but with a brief mention of the 15-note scale) is on Dave Keenan's page: http://users.bigpond.net.au/d.keenan/Music/ChainOfMinor3rds.htm

72 works well as a tuning for two different versions of the 7-limit
kleismic family. One has octave equivalent wedgie <<6 5 22...
("catakleismic" = 53&72) and the other, much less complex but also
much more out of whack in the 7-limit, <<6 5 3 ... ("keemun" = 19&34.)
The difference is that in keemun, we take three 6/5's of 316 2/3
cents, 19 steps of 72, to be the 7/4. This gives a 7/4 of 950 cents,
which is quite flat. Otherwise we can use 58 steps of 72, 966 2/3
cents. This is about two cents flat.
It's also possible to use 72 with 59 steps as the 7/4, which tempers
out 50/49. If you want to do 50/49 planar and are much more concerned
to get good triads than good 7 harmonies, not a bad choice. More
on-topic, however, is to temper out both 50/49 and the kleisma. This
gives <<12 10 10 -12 -18 -5||, the 4&38 temperament, with a 6/5
generator and a half-octave period. This temperament does not seem to
have a name, but it appears to be usable, and 72 is a poptimal tuning
for it. Using all three versions of the 7/4 would certainly be
possible for the ambitious.
