Sure, we're reading them
One option for the base might be to use pigment based (opaque) rather than dye based (transparent) toners. That way you don't have to go dark and the flaws will be hidden. So will all the grain but I'm guessing that doesn't matter at this point.
Mohawk calls them 'Tone Finish Toners' and you've got quite a palette to choose from:

Perhaps 'Medium Red /Shading Mahogany' ?
