Sorry, I did not read carefully.
You can go up several levels but down only one level.

implementation sketch:

* a new option to "include"::

   :relative-section-levels: <offset>

* push the current level and adornment-style--level mapping,

* read the to-be-included file into a list and append an "end marker",

* start a new adornment-style--level mapping

* section_level = parent_level + offset + child_level

* when hitting "end marker": pop section level and adornment-style--level
  mapping
