Out of curiosity, since I can't think of an example..

Lets say we have a {-bogh} phrase, e.g. {bartIq leghbogh vIghro'}.

Is there a rule which prohibits, one of the nouns having a type-5, e.g. {-'e'}, *and* at the same time the other noun having a type-5 too, e.g. {-mo'}, {-Daq}, {-vo'}, {-vaD} ?
