How Crazy Is This Idea?

So here's my idea that I'm trying to make a reality. Right now I have an 80 GB Western Digital internal hard drive that has been taken out of a desktop computer. I'm using a 40-pin USB adapter to connect the hard drive to my laptop, virtually making the internal drive an external drive. Now here's what I want to do: I want to partition the drive into four partitions and install Windows XP, Windows 7, Linux, and Snow Leopard on it and have them all be bootable from any computer via USB using a bootloader (Chameleon).

Thoughts? Help? I'm sure it's been done before. It's definitely possible, I already was able to install XP on the drive by editing a few files on the installation disc.

Well, it really isn't possible, or at least practical. The biggest problem is that you can't really move an OS that was installed on one hardware configuration to another hardware configuration without major problems. Another problem is that OSX has to be modified to either work on an AMD PC or Intel PC, you can't have an install that runs on both. Also, running an OS off of a USB device is generally slow and not really recommended.
