OK, well, without looking at your code I don't know if this is
applicable, but I did write the gcore code so as to use callbacks.
It was intended to be extendable, so that whatever needed to be
done per-section(segment) could be done by the callbacks, which
you could supply.

The callbacks supplied are for elf, for instance, which
is the only object format that I directly addressed, but
I would hope that callbacks for other formats could be
made to fit.  I was intending, for instance, to implement
a callback for remote targets that would simply read the
memory from the remote-writeable sections and copy it into
a file.

Can this not be made to work for you?
