Is there a way to fill in just the middle part of a half note (or whole

too) with white? I have tried \whiteout, but that gives me white around 
the
notehead as well.

Here's an option:

%%%%
\version "2.20.0"

whiteoutHalfNote =
  \tweak stencil #(lambda (grob)
    (grob-interpret-markup grob #{
      \markup \combine
        \with-color #white \musicglyph #"noteheads.s2"
        \musicglyph #"noteheads.s1" #})) \etc

{ \whiteoutHalfNote c'2 2 }
%%%%

This uses the quarter-note head to whiteout the background and then 
overlays the half-note head.
