Physics would confirm the rear.
Big tire up front used to be fairly common in BMX racing, in the 80s, it's what I ran as well. the wider tire was to give better traction in corners. A smaller tire in the front will work fine. I doubt you will even notice any difference with a 25 up front and a 28 in back. Of course as others have stated, the larger tire will soak up bumps better, provided of course the pressure is lower with the larger tire, which it really should be. In practice, a 25 and a 28 won't give a great ride anyway, for people like me who are used to much wider tires.
Put whatever combination strikes your fancy, and ride on.
