Yes they will work great! But they will also look "big" on wall whether that is or isn´t issue for you.
To give you some idea here is 3020 and 3010 high up on wall as front height (atmos) which look quite massive for typical lounge setup and the surround channels would be likely 1-2feet higher from seated ear height on wall.
Thanks for that! I have the space. I'm going to put the brackets up in the yellow marked areas in the photos below. About a foot above seated position. The front 3020i will be mounted on stands left and right to the hung tv.
