One thing I am thinking about: making the citation centered and leave the person right justified. Or is that a bad idea?

I made it:
\define[2]\epigraph{
  \blank
  \startframedtext[middle][frame=off,offset=none,width=fit]%
  \startalignment[middle]
  \startcolor[darkgreen]#2\stopcolor
  \stopalignment
  \startalignment[flushright]
  {\it #1}%
  \stopalignment
  \stopframedtext
  \blank
}

I think it does not look bad. But I have to let it grow on me.
