Staircase Ledge Decorating Ideas

I am lucky to have a grand curved staircase in my foyer, but not so lucky that the same staircase comes with a ledge. Seriously, there must be a way for a builder to eliminate it. A few people I talked to actually think a staircase ledge is a bonus feature. Sigh...we are obviously not talking in the same language. Anyhoo, I have to work with what I've got. So this is the staircase ledge I referred to, a completely useless but very visible little nook from the entrance.

A more close-up look at the ledge: do you see the silver-leaf urn with faux cedar plant in it? This is something I thought was cool a gazillion years ago.

I am struggling to figure out how to decorate this tiny little corner. Here are the options I am considering:

Option 1: display a Roman/Greek bust sculpture on a column/pedestal, like this Bust of Greek Goddess Ariadne from Restoration Hardware.

Option 2: display a group of bust sculptures on pedestals of different heights, like in this picture from Wayfair.

Can you tell I am obsessed with head busts lately? I can't think of a better place in my house to use them.

Option 3: display a group of tall vases of various heights. I've seen numerous houses with vases on staircase ledge, so this is a safe and proven solution. It's also very predictable and mainstream. Part of me yearns for something a bit more classic and extraordinary.

Option 4: add a tall (real) house plant. We have tons of natural light into our foyer year round, so a house plant will thrive at that spot.

Option 5: nothing on it, leave it empty. Let the useless space be useless.

So what do you think of a staircase ledge? Which option would you go for?
