VR, in its current form, sucks with or without AR. The reason it is such an unsatisfying experience has nothing to do with isolation and everything to do with the fact that you have to drape some cumbersome piece of hardware onto your head that, in my experience, has a tendency to fog up and capture condensation on your face after extended sessions. How anyone finds that remotely enjoyable is beyond me.
Another problem with VR (at least for gaming) is the absence of high fidelity games, or any compelling apps really. Sure, there are great games on the platform, but everything I've played in VR, such as Thumper or RE7, has been much more enjoyable playing in higher resolution with better IQ on a TV/monitor without some bulky, increasingly damp headset and wires all around my face. VR hasn't been an enhancement, but a hindrance to my enjoyment of these games.
So to answer your question, OP, AR enhancements will not suffice to get me to invest my time or money into VR. It would be a necessary feature for me for sure, not because I need to see anyone (I usually game alone in my office anyway), but to see the drinks and snacks I consume during a long stretch of vidya. However, I would also need VR "headsets" to be much less obtrusive and as easy to put on and remove as a pair of contact lenses. And they will also need to be capable of high fidelity graphics as well (I need to feel like I'm there in a living, breathing world--not the jaggy, blurry, or basic looking crap we're getting now). Not sure I see that happening in my lifetime but would love to be wrong.
