If I were the guy designing these starships that are supposed to last for the better part of a century, and some idiots kept blowing up the ones named Enterprise after just a few years of operations, I might indeed forward the motion that the next one be named something else. The USN isn't too keen on reusing the name Intrepid, either... (Diane Duane once inserted the "Evil I" remark into a Rihannsu book, now didn't she?)
OTOH, it is interesting how Starfleet had so many back-to-back Enterprises on two occasions in its history. Have novels touched on why the E-B was named that, after the seemingly premature retirement of the E-A? Or why the E-E got the name even though the E-D was lost in something of a disgrace?
