Question
According to riwaayat hafs, do we not have 3 categories concerning the idghaam kaamil/naaqis?

Being:

Idghaam kaamil bighunnah (non, meem)
Idghaam naaqis bighunnah (yaa, waaw)
Idghaam kaamil bighayr ghunnah (laam, raa)

Answer
Assalaam alaikum,
The above applies for the idghaam of the noon saakinah and tanween into the various letters noted.  Most scholars would agree with the categories, however, there are some-a minority- that claim that the ighaam of the noon saakinah into the noon and meem is naaqis.  
Jazakum Allahu khairan. 
Wa assalaam
