The subject of "imitation" has been largely discussed here, you don´t have to "imitate" anything, your lures "imitate" whatever the fish thinks, we really don´t know what a bass thinks when it sees a lure, so it´s all speculation, what you really need to know is that lures catch fish and it has more to do with who is behind the rod handle than what/how the bait looks like or you make it look like.
In my neck of the woods bass have never seen trout, salamanders, shad, perch, walleye, pike and so and lures that "imitate" them catch fish as well as those who "imitate" what bass may eat in the waters around my neck of the woods.
