[Tlhingan-hol] using adverbials or {-qu'} with comparison?

[De'vID]

Can someone remind me whether it's possible to use an adverbial with a
comparison? Or attach {-qu'} to {law'/puS}?

If I wanted to express "the time to do this mission is much more than
the time we have", would it be:
tlhoy Qu' poH nI' law' poH wIghajbogh nI' puS.
Qu' poH nI' law'qu' poH wIghajbogh nI' puSqu'.

Or something else?
