(Please be reminded that I'm not a lawyer)

This example is interesting. I think I am granted to reproduce those two separate works of 
the same substance ("verbatim copying in quantity" in GFDL's sense). Do I have the right to 
combine the resulting two copies into one? None in either license seem to allow me to do that. 

If the original two poems were dual-licensed, would it be any different? I am not sure, 
but perhaps not. 

Since I do not have enough expertise to answer this question with certainty, 
I tend to think that a safer approach to dual-licensing is to release a work under 
a meta-license, or to request CC & FSF to insert a dual-licensing clause in their license 
texts. I sketched those ideas here:
