Yeah that was the idea behind ExP (whoever actually innovated that, I don't think it was DAZ).  If you understand that structure of how DAZ gets their "updater" utility to read in new *.pz2 files and inserts them into a target CR2 then you could conceivably convert that stuff, I haven't looked at it since I have no use for it.  I'd suggest you PM Ralf and ask him if his utility can make this task easier, if you're not utterly against even thinking about it.  There's a lot of information that I'm totally not interested in reading myself about ExP here:

If you're asking about the generic/community channels (not sure):  There are 50 "data" channels (PBMDC) and 50 "control" channels (PBMCC) in each body part except head/neck, which has 70 of each.  What do you want to do exactly?  It's sounding like you want to convert your set of morphs that live in these channels to unique/reserved internal names so you don't have to worry about that kind of conflict in the future?
