Yes, good idea!
If Christopher allows to let another person know his postal address the member who will send him the print should pm his address to another partecipant who will send him another print.
OR they could exchange their send-to address.

for istance:
Laurent have to send the print to Christopher; Laurent will choose another member (No Digital, for example) and pm him Christopher's address and Christopher will receive two prints.
The other possibility is that Laurent and No Digital will exchange the addresses (No Digital will send ti Christopher, Laurent will send to the member who, originally, No Digital should send the print).

Of course, only an idea...
