Yes this is the kind of changes required. I was too lazy when I added the NB-IoT support in MAC and RRC dissectors and did not do this change (I'm calling them separately and not using the RRC sub dissector call from MAC one). Presumably the same kind of changes must be done for other channels (PCCH, CCH, DCCH). And RLC / PDCP dissectors will require modification also.
Are you willing to work on it and submit a patch in Gerrit?

Pascal.
