You may be right, but what do you mean by “consistently translated as {pIraqSIS} elsewhere”?  The only example I know of is from Klingon Monopoly:

 

pIraqSIS HoS waw' ghajlu'chugh, loSlogh boq'egh mI' naghmey mI'; chen qav'ap

If Praxis Energy Facility is owned, rent is 4 times amount shown on dice.  (MKE)

 

FYI the paq’batlh example is:

 

pIraQSIS maS bIngDaq pIgh rur SaqSub chIm choSlu’pu’bogh

The Saq'sub lay empty and desolate under the Praxis moon.  (PB)
