Honestly it's very doubtful that they would have been able to make enough of an improvement to make it successful. Most of the problem was the marketing, which really overpromised what it could do; they tried to pretend it was a virtual reality machine when in reality the most it could do was display low-resolution graphics with the illusion of depth and none of the core technologies needed for VR like head tracking or actual realtime 3D graphics.

It was more of a toy than anything else, and if it came out as a toy instead of a game system we would have thought of it as being much more successful.
