I agree with Geneadiva's comments on researching and documenting these older profiles, as it can be extremely time consuming. And PGM have even stricter criteria as to sourcing.
On that note, in the two years you have been waiting for the merge, what have you yourself done to improve the profiles as far as research and notations. Sometimes that is the best way to start, to make some profile improvements by sourcing what's there, and adding sources to the various marriages/children/history etc. to one of the profiles to confirm the often scanty data..
