Wouldn't the epigenetic modulation have to be implemented in germ line cells (in testes/ovaries)

Yes. But that’s the entire point: epigenetic factors can and do affect gametes. You can have a surgery that results in DNA methylation that in turn affects your sperm that in turn gets passed to your offspring:

Obviously, genetics is still by and large the main determiner, but epigenetics can result in genes being expressed or silenced in offspring.
