Epigenetics as a way to neutralize GM foods?

I just learned a little bit about EPIGENETICS,

which involves not the genes but the environment around them that influences their expression.

Here's a definition from an article:

Epigenetics literally means "above" or "on top of" genetics. It refers to external modifications to DNA that turn genes "on" or "off." These modifications do not change the DNA sequence, but instead, they affect how cells "read" genes.

In a documentary I'm just watching on alternative Cancer therapies, it's mentioned that epigenetics can be used to suppress expression of some genes.

So just having this wild thought:

What if this science can be taken to the fight against GM foods?

What if epigenetics can be harnessed to suppress the expression of the rogue genes in GM crops, like BT gene in BT-cotton, BT-brinjal, etc?

What if by doing so we can "neutralize" the damage done to crops, seeds that have been infected with the GM strains?

My understanding of this is quite raw right now, of course. But just had this idea so I thought I'll write in "into the ether" ;)
