There are 2 causes of "cancellation". One isn't really so much a cancellation. The high and low pressure zones that occur with a room mode are fixed in location and moving the speakers won't change them in the slightest. There is also a cancellation that occurs for the frequency whose wavelength is 4 times the distance of the speakers from the wall behind them. The frequency of this wavelength will change as you change the distance between speaker and wall but you can't avoid the cancellation by doing so. All you can do is change it's frequency. That can be used to advantage at times by moving the speaker until the frequency at which this cancellation occurs coincides with the frequency of a troublesome room mode peak so that you use the cancellation related to speaker distance from the wall to weaken a peak related to one of the room dimensions.
The problem with moving the speakers to weaken bass in this case is that the room is small and that means that there's less flexibility in how much distance you can place the speakers from the walls. In many cases you can't move them far enough from the wall in order to weaken the bass support they get from the walls sufficiently to solve a problem without ending up with them so far from the wall that their position is simply unworkable in the room.
