This looks like a good solution to me.  Thanks for looking into it and coming 
up with a fix!  That recursive map function is especially nice.  For the name 
of the markup command, I’d like to suggest \outline since it is more in line 
with the names of other markup commands.  

It might also be good to let the \whiteout markup command respond to color 
property overrides, but that’s a separate issue.  And I suppose it raises the 
question of whether to provide both, which is a matter of how sweet or bitter 
to make the syntax.  For example:

\markup {
    \override #'(style . outline)
    \override #'(thickness . 3)
    \override #`(color . ,red)
    \whiteout ''text with red outline"
}

\markup {
  \outline #3 #red "text with red outline"
}

Cheers,
