Perhaps just as a slightly "cleaner" version, might using
"HED-group peridotite" rather than "HED-clan peridotite" be
a bit better? 
 
 
>From my understanding you would say clan.  Like eucrites are a clan, and within eucrites you have several groups or different types of eucrites, such as Polymict Eucrite or Unbrecciated Eucrite.  Given a few more finds (or more study?), the different Peridotites would receive groups names.  It should be noted that nobody calls eucrites, "HED-group eucrites", so would not the name, if decided upon, just be "Peridotite", or should the HED-group part be carried to not confuse people with an earth peridot?
 
Personally, I still like the thought of using historical names for clans, and then the more scientific words added to define the groups.  I do however see logic in using names that are easy to recognize for the average geologist.
