For some reason, what you're wanting to do just feels like your going to have failure.I don't have a ton of experience with water based finishes, but I did attend a seminar on recoating with water based finish. The recomendations of that seminar were to use a bonding agent when recoating over polyurethane or aluminum oxide with water borne finish.
If you decide to go with oil based finish, I'll be able to offer a lot more advice. I've got a lot of experience to draw from there.

Mineral spirits & water based finish are not a good combination. I do exactly what you desribe to give clients an idea of what they're floor will look like, but I use oil based finish.
