Anything is possible. Will you get sound that relates to the (quite high) price of the Arc? Of course not. Putting a soundbar behind the TV will stop the sound it emits form reaching you directly. Atmos sound, if you use it, will probably also be worse.

Your TV needs to be placed higher up.

Putting one of these under the TV feet has been recommended:

I picked up a Sanus tabletop TV mount that raised mine enough to clear my Arc. A nice addition I can now swivel and tilt the TV.

Very good.
