I wonder if putting it to sleep would help, as that saves a copy of
memory for the restore?
Surely, hibernated system saves all the memory in a file.
That was very useful in Windows 3.10 to unprotect some programs,
originally packed and protected from debuggers. Memory dumps
were perfect to analyze!
I think, that feature can help you, too.
At least, it is much more useful, than nothing we get if the system
is just shut down.
Normal sleep on a non-battery machine keeps power
to the RAM. However, you can change the power
settings to make it save to a file. It is
explained here:

Of course the question is what happens to the
sleepimage file after you wake the computer from
sleep? Does it get modified, or does it stay the
same as when it went to sleep? (I know it does
not get deleted.)
The there is the question of whether the mapfile
data is stored as text or in binary? I imagine it
is binary which may make it a bit difficult to
identify which part of the 8GB memory dump it is
in. And also, it is needed to be in text form for
ddrescue to use it.
