Not in general, because it can't sanity check the path so it doesn't
know what to do to it.  But you can handle some simple cases:

if [[ ! -e $1 ]]; then
  local dir=${1:h}
  if [[ -d $dir ]]; then
    dir=(${dir}(:a))
    1=${dir[1]}/${1:t}
  fi
fi

This works for names without a slash since ${1:h} returns ".".
