True.  The best bet for restoring the G-15 would be to construct a
drum emulator that would interface with the rest of the machine
using the same timing and signal levels as the original drum.  Use
that to get the rest of the machine running.  Then if the original
drum turns out to be unrestorable, we still have a running G-15,
and if the original drum can be restored, the emulator can still
be used to minimize any additional wear and tear on the original.

I have no idea, however, how much of the original software still
exists.  I've got a few of the paper tape cartridges and I've seen
some references online about software, so there is hope.  Of course,
writing software is a lot more fun than running old software, so
even if nothing still exists, restoration would still be very interesting
to consider.
