Hey Alex,
I haven't re-traced a PCB but I would probably do the same thing Jim is
suggesting - import a graphic into my CAD program and trace it over with
metal. EAGLE has lots of scripts available to import graphics, DXFs and do
other completely different things. You can also write your own!
I'll be able to try converting his scans to 2-color, then he can import
them using his scripts. I won't have tim to do the tracing with metal
though.

Anders, mind sharing which method you use to redraw a
PCB? I have lots of
interest in this subject.

Hey Jim,
I can probably do this for you but I'm pretty busy for the moment. What's
your desired timeline? I've been using EAGLE since 2005 so I'm familiar.

If this is a one off all you need to do is print
the negatives on
transparency material with a laser printer.
The laser printers tend to have a little more opacity than ink jets do
but
I have done this with an ink jet
printer as well. I also once plotted directly on the bare copper with a
sharpie and had it turn out ok.
Align the negatives on the sensitized board stock.
Expose.
Develop.
Etch.
Drill
Solder in your feed throughs.
Put the parts on the board.
Debug
If on the other hand you want to make even 5 boards you would be better
off
with your approach.
Best wishes!
