As your chart shows, it's pretty easy to read a regular d6 as a dF.

The Genesys dice are a little asymmetrical -- probably intentionally so, so the expected result is "success at a cost". An even number of ability dice and difficulty dice average out at 1 success and 1 threat. *The actual result may vary widely, of course.) Other than that, the "good" and "bad" dice are more or less symmetrical. I don't know of an easier way to read them with ordinary dice than to use the chart in the Genesys Core book. You could reorder the faces to make them a little easier to remember, but still a lot of memorization.
