Copy all event handlers from one control to another at runtime

I'm trying to copy every event handlers from one control to another (same type). I found several exemple to do it with Winform but nothing for WPF...

<Window x:Class="WpfApp1.MainWindow"
    xmlns="http://ift.tt/o66D3f"
    xmlns:x="http://ift.tt/mPTqtT"
    xmlns:d="http://ift.tt/pHvyf2"
    xmlns:mc="http://ift.tt/pzd6Lm"
    xmlns:local="clr-namespace:WpfApp1"
    mc:Ignorable="d"
    Title="MainWindow" Height="350" Width="525">

    <StackPanel x:Name="panel">
        <Button x:Name="btn1" 
                Content="Button 01"/>
    </StackPanel>
</Window>


using System;
using System.Windows;
using System.Windows.Controls;

namespace WpfApp1
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            btn1.Click += (s, e) => Console.WriteLine("Button pressed");

            AddButton();
        }

        private void AddButton()
        {
            Button btn2 = new Button() { Content = "Button 02" };
            panel.Children.Add(btn2);

            // Copy all event handler from btn1 to btn2 ??
        }
    }
}

The thing is that I don't have access to any handlers method name, as i'm suppose to copy the event handlers from another class...
