Correctly removing the default Python installation

I intend to replace the default Python installation with the one from Homebrew. Below is a list of steps that I want to take, but I first want to make sure that I'm not doing anything destructive, which is why I'm posting this question. :-)

1. 
   

   The Python.framework folder is located in /System/Library/Frameworks. Is it okay to remove it? Being under System I worry that I might break something.

   
   


2. 
   

   Remove all Python related files from /usr/bin. In my case (and probably everyone else's), I'll be removing everything given by ls -l /usr/bin | grep python:

   
   
   
   
   • python
   
   
   • python-config
   
   
   • python2.6
   
   
   • python2.6-config
   
   
   • python2.7
   
   
   • python2.7-config
   
   
   • pythonw
   
   
   • pythonw2.6
   
   
   • pythonw2.7
   
   
   
   


3. 
   

   In my case I also have pip installed. The only reference to pip I found is in /usr/local/bin. To also uninstall pip I'll delete the files given by ls -l /usr/local/bin | grep pip:

   
   
   
   
   • pip
   
   
   • pip2
   
   
   • pip2.7
   
   
   
   

Is there anything else that I should be doing to do a complete and correct uninstall? Are there any dangers that I should be aware of?
