Tiny tiny inglets of green onion over the top would not be "over the top,"
but I'm hesitating about the chipotles--maybe in a small dose, instead of Tabasco? It's the abodo sauce they can them in that I'd be concerned about. But I hope you try them, one way or another.
BTW, when I've done this with jalapenos, I've subbed queso fresco for the feta, and I've also used those colorful mini bell peppers from Costco, halved.
