Dear List,
A lot of good suggestions for naming this new group are rolling in and we are pleased with the turn-out. We thought the NomCom had something to do with naming of meteorite groups because many submitted description titles have been changed after NomCom voting when new meteorites were submitted. One example is NWA 1459 which was submitted as an "Olivine Diogenite" and was published as "Diogenite, olivine-rich"...

The Meteoritical Bulletin is an edited publication. Basically, it is up to the Editor, acting on advice from the NomCom and the person describing the meteorite, to use whatever classification terms she sees fit. In fact, if somebody names these meteorites Bozoites, the Editor will still call them by the term she thinks most appropriate. I will certainly advise her to avoid new trivial terms unless they come into common usage.
I want to emphasize: the names eucrite, diogenite, and howardite are 19th Century coinages. They are remnants of the old Rose-Tschermak-Brezina classification system, most of which is long-dead. They only survive because ancient traditions die hard, and until the 1970's there were very few achondrites available for systematic classification. It is not reasonable to coin new 19th-C style names for things. Science has progressed too far.

This is wrong. New types of martian meteorites are now classified as, e.g., ALH 84001: "martian orthopyroxenite." Trivial names have also not been coined for lunar meteorites: they are classified as "lunar basalt," "lunar anorthosite," etc. The names of HED-clan achondrites should follow suit. Once we're sure they're from Vesta, they should be called "Vesta peridotite" or some such. For now, terms like "olivine diogenite" or, a better alternative, "HED-clan peridotite" serve to identify both the mineralogy and parent body.
