Not very likely.
What's really needed is yet more info.
A scanner that can do RGB + several IR bands would really help, as it can
pick up data that's not obsucured by stains, rather than trying to
see through the stain.
Seeing what the real resolution that can be got isn't to hard.
A human hair is about 0.1mm in diameter.
Tie a knot of several hairs, and see how well it resolves.
