After trying to use this, I came to conclusion that imenu--index-alist is unsuitable for outline-minor-mode because imenu has a different hierarchy than the source files, so outline-level can be only 1. But without different levels for outline-level it's quite useless. However, in the opposite direction mapping the outline hierarchy to imenu is possible, and outline-imenu-generic-expression does this, but only to a flat list that is sorted alphabetically.
