And U+0304 COMBINING MACRON is missing.

But the missing glyphs can be constructed manually:

\DeclareTextCompositeCommand{\=}{EU1}{V}{%
  \leavevmode
  \begingroup
    \sbox0{^^^^012a}%
    \sbox2{^^^^02c9}%
    \sbox4{V}%
    \rlap{%
      \hbox to \wd4{%
        \hfill
        \raisebox{\dimexpr\ht0-\ht2\relax}{^^^^02c9}%
        \hfill
      }%
    }%
    V%
  \endgroup
}
\DeclareTextCompositeCommand{\=}{EU1}{y}{%
  \leavevmode
  \begingroup
    \sbox0{^^^^016b}%
    \sbox2{^^^^02c9}%
    \sbox4{y}%
    \rlap{%
      \hbox to \wd4{%
        \hfill
        \raisebox{\dimexpr\ht0-\ht2\relax}{^^^^02c9}%
        \hfill
      }%
    }%
    y%
  \endgroup
}
