I'm sure that is possible, but you'd need to make some code changes (and 
consider whether an arbitrary binary blob, containing nulls, is really a good 
idea in a std::string). The code changes should basically be taking the 
existing output writer and copying in to a memory location instead. I don't 
see you'd need to make any real popper changes. How you integrate that depends 
on the application you're trying to create.

What is the end-use for this?
