no.

duplicity deals with "dumb" backends and solely uses them for file storage. for 
this design to create a synthetic full you would have to transfer the whole 
data over the line again anyway completely.

however, it'd be possible to implement that for the rare cases that users have 
shell access to their backends and can have a duplicity instance running 
locally there.
