Is there a way to prevent core saturation (from high frequency DC current) by placing a high pass filter on the AC transformer?

I don't want to fry people's electrical wires. Just want a high frequency modulated dc signal to get to the customer without destroying vital electrical infrastructure(and getting sued).

Think a bit. What are you talking about. It is either DC (f=0Hz) or high frequency. It can't be both.
Any transformer (except coreless ones) can be saturated if the current is high enough. Regardless of frequency. I doubt that your supposed communication circuit delivers enough power to do so.
Look up power line communication.
