Smell-o-vision has been around in various forms since the 1950s.
The biggest problem that I can find with it (and the reason most theaters gave up on it) is, what happens when you're in a room that is not properly ventilated? Because although chocolate and tire rubber and campfire smoke can all smell nice separately, you really don't want to have them all mixed up together.
There's also the small matter of what happens when the chemicals run out. How do you replace them? Printer ink costs more than caviar, imagine how much they could charge for this stuff.
