Wow, you are certifiable...that's good...because if you aren't now, you certainly would be after trying to put a Porsche transmission into a Subaru. We're talking major guttage, and one of a kind custom made parts. Of course it's possible, but for the cost and trouble, why wouldn't you just implant an STI 6 speed? It certainly would be cheaper, and arguably the new 6 speed rivals conventional Porsche transmissions in quality.
