How can I modify all jQuery functions, which return object with DOM elements, to return additional data?

Question

I'd like to modify all jQuery functions, which return object with DOM elements, with some additional data, so whenever I'd call jQuery functions, which return jQuery object with DOM elements, like $(selector), find, filter, etc. and would normally get a standard jQuery object:

{ 0: DOMElement1, 1: DOMElement2, 2: DOMElement3, ...}

i'd like to get a modified jQuery object instead, e.g.:

{ 0: {0: DOMElement1, num: 1}, 1: {1: DOMElement2, num: 2}, 2: {2: DOMElement3, num: 3}}

I tried to modify the $.fn.constructor:

(function($) {
   var orig = $.fn.constructor;
  
   $.fn.constructor = function(e) {
      var origApplied = orig.apply(this, arguments);
      
      console.log("Constructor called");

      var outputData = $.map( origAppliedArray, function (value, index) { return {[index]: value, num: index} });

      return outputData;
   }
    
})(jQuery)

The constructor is called every time the find or filter functions are called, but the code only returns an array with DOM elements.

How could I achieve the mentioned result?

It would work if you would monkeypatch $.fn.init instead of $.fn.constructor.

Disclaimer: this is not advised. It will be confusing to those future developers that get to maintain your code after you. It will also break code that would be expected to work, like for instance chaining (one of the great features of jQuery) and passing arguments that are jQuery:

$("#container").append($(".copyme").clone());
