Bose question

I’m looking to expand my home theater by adding 4 atmos speakers. I was looking for a cheap solution as I don’t think these channels need to be up to par with the rest of the speakers. 
Would it be possible to add Bose acoustimass cubes to my conventional AVR? 
If this isn’t possible or advisable, what would be a good alternative ? I’m looking for something small and decent looking, will be in my living room. 
System consists of Vienna acoustics speakers, Rel, and NAD T778 AVR.
