This would certainly work well. It is going to combine a lot of elements that will help fool the viewer. First, The floors would probably be wood plank, which will give you lots of lines to draw the eye back into the painting. Then, you have the bowling pins, which make a great focal point.
Your other ideas sound good, too! Patrick Hughes has a train tunnel in his book, which looks really cool. Perhaps you should do the hallway with doors- The dream could be a sign??
