Was wondering if I could do this

Solution
I think you could.
You would get more maximum output but perhaps lower sound quality as the speakers would interfere with each other.
You would want each speaker playing the same channel in the same place. For example you would have three center channel speakers. You could place them above and below the display, There would be some cancellation since they are play the same thing.
The subs could be placed in different locations but the others would have to be close to each other.
