I could see using -qu' on a type-9 suffix to emphasize a condition (Daleghchughqu' - "IF you see it", or perhaps even "IF AND ONLY IF you see it"), purpose or the like, though it does seem a bit unnatural to my ear; something you wouldn't hear very often.

It would sound unnatural because it's ungrammatical:

Rovers are verb suffixes which do not have a fixed position in relation to the other suffixes following a verb but, instead, can come just about anywhere except following a Type 9 suffix.

You could break the rule anyway for rhetorical effect, and in informal or dire situations the grammatical error could probably be ignored. But you'd lose points on your Klingon 101 midterms.
