If you want to do this I would advise you to load one of the suites onto an external or different internal drive.. reason being, that since you are using the same serial number for both copies, and the myriad of support files would be somewhat duplicated, it may be best to separate them completely onto two different volumes.
You can load a complete copy of MacOS X along with Studio 2 onto a second drive and boot from that drive when using Studio 2. later on move Studio 2 to your home directory.
