Short answer no.

Long answer follows.

Quoting from 
http://pip.readthedocs.org/en/latest/reference/pip_install.html#options 
for the --pre flag "Include pre-release and development versions. By 
default, pip only finds stable versions."

Looking at the output above and at the URL you quote I doubt that it'll 
work for me as it seems to be Python 2 only.  The URL also lists a load 
of dependancies and I've no idea whether or not you could get them for 
Windows or not.  There's only one way to find out, so would you like to 
give it a go and let us know how you get on?
