That looks like a good start. Just start adding about 2 ounces of PB at a time until you get the taste you want (and maybe some garlic powder to help enhance the PB taste).
On a side note - when I was a teenager we were visiting my sister in San Francisco (1977). We went to eat at a nice place called the Cliff House - their specialty was omelets. Everybody at the table groaned when I ordered one - Peanut Butter and Jelly omelet. Surprisingly, it was not bad. :thumbup1:
