You can try matchadd() and experimentating with the priority instead
of using a syntax match. I'm not sure whether you can override the
colorcolumn, though, it may be always on top by design.

I personally gave up on my whitespace highlight patterns in favor
of :set list, and a 'listchars' setting which actually looks nice and
includes a "trail" definition (using a bunch of fancy Unicode
characters).
