Impressive analysis. I could have never thought that something like this is happening.

However I need to ask you:

Does this mean that in any noun-noun construction, the head noun is the second one ?

It's always the last one. (Noun-noun constructions can be strung together; e.g. tlhIngan Hol yejHaD is a kind of yejHaD; not a kind of tlhIngan or a kind of Hol.)
