This is an AWESOME IDEA!! But, you won't be able to buy them at actual Taco Bell locations. They've just released their own line of sauce-flavored tortilla chips available at your local grocery store. You have a choice between Mild, Hot, and Fire-flavored chips, along with a Classic flavor for those who aren't into the spicey ones.
According to Food & Wine, "the chips are crunchy and salty, and there’s a flavor profile here for every type of snacker."
The website also reviewed each of the flavors, saying that the Fire-flavored chips are bright red and have a little bit of a kick, but it's not as intense as such hot sauces as Tobasco sauce. The Mild-flavored chips have "a cheesier flavor and aren’t in the least bit spicy."
