You are already the third person suggesting it :)

Yes, it is possible. You can do it with your code. I still don't know if 
there is a will to modify:

   TWinControl = class(TControl)
     // ...
     property Controls[Index: Integer]: TControl read GetControl;

to

   TWinControl = class(TControl)
     // ...
     property Controls: IWinControlControls read GetControls;


Something like
   TWinControl = class(TControl)
     // ...
     property Controls[Index: Integer]: TControl read GetControl 
enumerator GetControlEnumerator;

or
   TWinControl = class(TControl)
     // ...
     property Controls[Index: Integer]: TControl read GetControl;
     property Controls: TControlEnumerator read GetControlEnumerator;

seems better suited from my POV.

(The same for TStrings.Objects etc.)
