Wireless / OLED / thicker, non-fresnel lenses - these are all nice-to-have things that add to the cost, and it's the cost that's putting people off the Vive headsets.
What SteamVR needs is a cheap sub-$250 option that is light, basic, and cheaper IPS like many of the $200-300 WMR headsets. I've used a couple and they're fine. If people like VR enough to expand their library they can invest in something nicer/wireless/OLED.
I would pay the cost if it delivers on this criteria ... up to $1,000 or so.
