First you have to install Windows on the SSD. You can't do it with Bootcamp, but you can use Hasleo's WinToUSB.
I can't speak to what would happen with your activation, though.
If you don't need the full power of your computer, you could use the Personal Licence version of VMWare, which is free, and install a Virtual Machine with Windows on it. That should be able to run on two machines.
