In Editor Scene View using Rift?

I think the short answer is "sort of" :-D.

You could use holophone3d's overlay app and set up two cameras with a little bit of separation, attached to an empty so you can move them together:

But I think the longer answer is "Sort of, but it would be next to impossible to use." You wouldn't see any of the interface windows (and if holophone updated the app to allow adding additional elements overlayed over the stereo image, itext may not be readable).

There are a few works in progress that allow some basic construction in runtime (Sixense has one that seems pretty far along, MakeVR), which I think is a much more workable solution than trying to use the Rift in the scene view.

I agree that this is an awesome idea, but it may be kind of hard to work like this. Both because of the Unity interface and also the low resolution on the Rift. What you can do is put the game window onto the Rift and still work on your primary monitor. So you could edit parameters in real-time, while you view on the Rift. This is how we've been developing, but of course you will have to remove the Rift briefly to edit things on the main monitor.

Well... I have an idea on this, but it'd take a bit of work. You could create an editor game object with two cameras like said before, and add a run in editor script to it that would control movement (you'd still have to program that, but it's not that hard) as well as create custom controls to do the basic transforms and such (which you would also have to program).

It'd probably be a pain to do, since you'd effectively be rewriting the scene view in the game window, but technically would work. It would be a TON of effort though.
