Two more examples of {latlhpu’}:

Heghpu'bogh latlhpu' ghuHmoH bey.  ghoS tlhIngan SuvwI' maq.
This yell ... serves to warn the other dead that a Klingon warrior is coming. (S31)

It looks grammatically correct to me. However, I would also prefer to use {latlh}, although I think it would be clearer to attach it directly to nuvpu', rather than making a compound with a relative clause:
{pa' Qotbogh latlh nuvpu'vaD jatlh...}

I also thought it was fine, but I'd say {latlhpu'} rather than {latlh nuvpu'}. 

Recall {DaSwIj bIngDaq latlhpu' vItap} (not {latlh nuvpu' vItap}) from Star Trek Constellations.
