If adding enough interactivity for VR is reasonable while keeping the price as it is right now, sure. But I've seen many VR games fail at this.
The bar for any VR project is quite high, there's some very complex projects out there with mediocre ratings for all sorts of reasons, like bad performance (often graphical or simulation related), lack of interactivity, boring visuals, obnoxious visuals, nauseating, unsupported controllers...
So sure, why not. But I wouldn't mind it if you decided to make a second game with VR features, keeping this one non-VR.
