downgrade mavericks to 10.8 w/o clean install

Is it possible to downgrade 10.9.5 to 10.8 without a clean install?

I need to optimize my computer to run FCP studio 3 (not FCPX) and I have been told that it stops working after 10.8.

I really need to know how to do this quickly as I have an editor flying in from Berlin to work on this project.

I don't want to get in the FCPX / FCP7 debate.

there has already been rough cuts and over 300 hrs logged and sorted with FCP 7

X is not an option.

Any advice is greatly appreciated.

thanks!

In order for internet recovery (using Command + Option + R) to install the original OS, remember that you will need to wipe your hard drive while booted into recovery (using the Disk Utility available in the Utilities window after connecting to Apple's servers).

As for your FCP question: might get more answers in the FCP forum....
