Doesn't the preview come out on the 1? So shouldn't it work then?
Also, if I take this and install it on my flashed 360, but share the HDD between 360's what will happen to the 360 I use for live?
No and no.
That would be the same as installing it to your flashed 360. Doesn't matter how you get the update to the other box. The HDD is just a means of storage.

Yes.
