In fact, such feelings might be better feedback than the buffet, blackout/redout indicators and stall horns we're currently provided by the game.
BTW, the consumer rift is said to be significantly lighter--likened to the weight of a baseball cap since it's mostly fabric--than the DK versions, such that whipping heads around to follow targets shouldn't be a problem even after hours of play.
As far as sensory feedback goesI will explain as best as I poorly can lol. Flying in formation is easy. Not because u can look toward wingman more easy, but because everything in game is HUGE compared to when you are looking on a screen. On a moniter screen it looks as if youre bobbing up and down and moving all over the place, because you can see so many visual references around, both in-game and out, in the rift these movements arent even noticeable. Aircraft seem much bigger, heavier, and slower, and everything happens much slower because of it. Whereas on-screen you were having to concntrate to maintain formation, in the rift it is one handed effortlessness. You dont even have to pay attention other than an occasional glance. Distance becomes a much more tangible thing, like when u look at your wingman next to you, you can no longer focus on the horizon behind him at same time the way you could on a screen. You have to refocus your eyes past him, and now hes a blur. Same way as looking inside your cockpit requires you to refocus your eyes. This is very noticibly different from on a screen where your eyes remain constant focus, and therefore you have many more visual references at once.
Its exactly this requirement to 'look and focus' on a reference that makes being in a spin so awful, (similarly to real life i would imagine). Every manouvre you make, you really need a reference point to hold onto throughout, something that's not really required with on-screen flying. This apply's to FSX and DCS as well. The huey in DCS is one of my favorite VR activities, but if you lose your visual references, especially on takeoff, you feel like you're in an elevator and the cable just snapped. Same as rolling scissors in AH made me feel when I lost the horizon, or FSX when you drop down into zero visabilty thunderclouds and start getting bounced around.
As far as weight, definetly a good thing to get lighter. DK2 feels pretty light when you first put it on, but after 2-3 hours in Elite you really start to notice it. Worst however is the thick pad around which gets really warm and makes your eye area sweat. (But nowhere else on your face bizzarely).
Google has failed me, so I'll ask here. I had assumed it was so but is Rift's head tracking scalable like TrackIR? I had assumed so but if it's locked 1:1, that kind of kills my interest quite a bit.

While I have never seen it, I can almost say with certainty that it will be scalable without too much difficulty. However I've never seen or heard of it being done, and i cant help wonder how your body/mind connection would react to that. 'Sim-sickness' as wiley put it is worst when your body and brain are fighting for 'who is correct'. Soon as you put rift on, EVERYTHING becomes real in front of you, you spend a couple of hours just trying to reach out and grab things. The ease in which control of your eyes and ears dominates your brain is astounding. The sickness occurs when for a split second, your eyes and ears lose 'control' of your reality, and things like your inner ear manage to start an argument. Your eyes and ears are telling your brain that you are upside down in a la7, (and you were believing it) but your inner ear suddenly said 'nah youre sitting in an office chair immobile bud', and you feel like you just fell off a cliff. Very similair to being falling down drunk I found. Anyway, point is, the more realistic the 'feeling' simulation, the less chance of giving inner ear time to argue, (Elite I believe is still considered the greatest success at this, people have played 12 hour sessions in the rift no problem), any sense of 'not real' is punished with game ending nausea. So, to answer the question, yes its doable almost for certain, but a 'simple' change like that could really blow your mind, and not in a good way.
The whole thing has some very unique problems and advantages that are still not fully understood.
