Imagine that you are rolling an Alpha release on an i386 box. You don't do that. Cross releases need much more work before that is feasible. As Mark mentions, there are many thigns that would need to be fixed. Also, the release process would be hacked, and you still wouldn't have a true "clean room" release since you can't build a "clean room" to run a fresh world in. >> Your solution does not work.
