Not sure, but my guess is no, not simultaneously.  You can, of course, transform 
each of the molecules individually or do the disappearing molecules in one 
procedure (with a custom [moleculetype] containing both molecules) and the 
appearing molecules in another (same approach) and sum the free energy change. 
I don't know if that will be equivalent to what you're needing to do, though.
