Monsters Inc: Ride and Go Seek at California Adventure?

Just when I thought I had seen all the concept art imaginable for Disney's California Adventure, I unexpectedly stumbled upon a great little website by Imagineer Julie Svendsen.
Although her site lists this concept art as for the Disneyland Resort's second gate, if you look closely, it sure seems to be for Tokyo Disneyland's Monsters Inc: Ride and Go Seek! If you click on the images for a larger view, you'll notice riders are holding flashlights and pointing at different objects.
The obvious question: Is Julie's site incorrect or did The Walt Disney Company's Imagineers originally plan Ride and Go Seek for California Adventure? Could it be that the originally planned replacement for the lackluster and strange Superstar Limo was really the new line buster at Tokyo Disneyland? One part of me says, "Nah, this is California Adventure after all". The other part of me knows full well that the Imagineers can do amazing things when given the budget and the support.
