The usual way to protect a regualtor against the output going higher than the input is a diode between output and input. In the direction that will conduct if the output goes high. The reservoir cap will then absorb the impulse. The bridge shouldn't mind.
BTW, you marked the reservoir caps 100n. While it's a good idea to put a 100n cap close to the regualtor input to stop it oscillating you'l want at least 1000u reservoir too.
