Are some female nouns in Bokmål more readily ''masculinized'' than the others? (conclusion)

This is the continuation of two previous posts.

As you've seen, Dagsavisen and Dagbladet online versions differ somewhat in the way they treat female nouns. We can't really say Dagsavisen is more ''radical'' than Dagbladet, or vice versa, because it depends on the specific word involved.  Dagsavisen's web ''corpus'' is not as large as Dagbladet's one, so sometimes there were very few forms found (for example: only one occurrence of dørklokka (with no occurence of  dørklokken), and no occurrences of  eggerøra (with only one occurrence of eggerøren). So, in cases like these, the Dagbladet ''online corpus'' seems to bear more statistical significance. 

Overall, these nouns are used predominately as female nouns, in both newspapers (English article left out):

moroa = fun; reka = prawn; søstra = sister; skuldra = shoulder; pølsa = sausage; underbuksa = underpants; kona = wife; bøtta = bucket; døra = door; buksa = trousers; jenta = girl; tåa = toe; bleia = nappy, diaper; bokhylla = bookshelf; hytta = cotage; trøya = vest; ferja = ferry; trusa = pants; kaka = cake; dama = lady; bløtkaka = gateau, cake; brygga = quay, jetty; dørklokka = doorbell; skjorta = shirt; stua = living room; senga = bed; nesa = nose; strømpebuksa = tights; tanta = aunt; gata = street; jakka = coat/jacket; klokka = clock;  silda = herring

These nouns are used predominately as female nouns, at least in one newspaper (English article left out):
