Good rationalization, but .... Water is very hygroscopic so any water in the system will be rapidly disbursed throughout he fluid. Even if water stayed a bubble (it can't) and it's coefficient of expansion was higher then brake fluid, the increase in volume would just push the brake fluid through the compensation port in the M/C and into the reservoir.
