Can I safely put two 4 posts in a 29-inch wide area with 12-inch diameter holes for a wall-mounted arbor with a bench?

Hey everyone,
I’m thinking about building a wall-mounted arbor with a bench like the one in the picture I attached. The plan is to have four posts for the bench placed in between the granite stones. The distance from the center of one arbor post to the next will be 24 inches. The width of the area I’m working with is only 29 inches. Do you think I could fit two 4-inch posts in that space? I need a 12-inch diameter hole for each post theoretically, and I want to use concrete footings to keep the posts above ground. Just wondering if this plan sounds feasible.
