De'vID:

QInvam luHevpu''a' latlh? pIm'a' QIn?

*Spam*Daq tetlhvam lulochbogh HochHom QIn'e' vIHev, Landau Martin je QInmey vIHev je. pImbe'.

By the way, two short questions:

1. Should *HochHom QIn* be considered singular or plural?

Unclear. We might suppose that HochHom X follows the same rule as Hoch X: including a plural suffix means to take most of the X's as a whole, while leaving off a plural suffix means to take most of the X's individually. I would guess, in that case, that the plurality of the phrase depends on whether there is a plural suffix. But we don't know for sure if HochHom follows the same rule; I suggest it only as a default position to take.

2. I guess there is nothing wrong with *(noun noun je) + noun* as a noun-noun construction? Are there canonical examples?

Nothing wrong with it. A canonical example comes from paq'batlh:

vaSvamDaq
    tuq veng je quvvaD
    Heghqangbogh SuvwI' tu'be'lu''a'

Is there nobody in this hall
    Prepared to die for the honor
    Of your tribe and city?
