No it won't work. It's mixing oil and water (literally). The common recommendation is to not thin waterborne finishes more than the manufacturer suggest, that's almost always less than 20% or so. More than that can screw with the chemistry. I'm guessing you just want to prevent grain raising (?). It might be just as easy to apply your first coat of waterborne, let it dry, sand it smooth, and your done (with the grain raising). The first coat locks the fibers on place to be smoothed out and seals it from further problems, continue to apply whatever number of coats you want.

Or he could make his first coat Sealcoat. It will prevent grain raising and will build finish thickness at the same time. Dries in less than a half an hour.

I thought he said he didn't have any shellac....
