Any time you bypass any type of regulator you risk putting everyone in the household in danger. For one, you cannot control the temperature of the water which, anything that is over 130*F (54*C) will cause scolding and blisters within just a couple of seconds. Second, if there is no regulator then how will the unit know when to turn off the gas so it doesn't boil the water? I would be concerned with potential gas leaks and over-heating which can cause the water heater to explode.
I would have someone else come out and replace the limiter. Bypassing is a temporary fix to a more permanent problem.
