If any morph data is contained in the CR2 (and normally there is, the joint-controlled morph data) then DAZ considers it a violation of their copyright to redistribute that CR2.  Joint parameters and the JSM magnets, they allow - else there wouldn't be any conforming clothing market.  I don't know EF's license but I expect it is similar.

If you want to hand around modified CR2s like you're discussing, you need to obtain permission from the licenser (DAZ or EF) or else find a way to strip out the morph data and leave the user with a way to get it back in, if they own a licensed copy of that figure.  One method of doing this is to use RTEencoder, an example of which is here (regarding Apollo Maximus, and with Anton Kisiel's support):
