r.js path switching

gistfile1.js

// Is there a way to change a path for a specific module during the r.js build process?
// So that a module with a dependency of 'jquery' can be used with two versions? 
// I have tried to show what I would be after with lines 16-18

({
  baseUrl: "./",
  paths: {
    "jquery": "jquery/jquery-2.0"
  },
  modules: [
    {

    {
      "name": "app/legacy",
