This is a blast from my childhood past.. love frito pie. We ate it often growing up in Texas... may have had something to do with elderly relative having original stock in the Frito Lay company. Who knows, but it was good.
Walking tacos - excellent idea! I wouldn't even go to all the trouble of the recipe with all 18 ingredients. I'd just get a packet of taco seasoning, beef, then use lettuce, tomatoes, cheese, jalapenos, and put your fixings in the bag with the fritos and let it rip!
