(History buffs and authorities will have to excuse me, since all five reigned after Pompeii was already covered by ash. This will just have to come under the heading of artistic license!)
In fact the Emperor Titus, son of Vespasian, ruled when Pompeii was destroyed. Titus was succeeded by his brother, Emperor Domitian, whose reign was one of terror, at least for everyone in close proximity to him.
Nerva (30-98 A.D.) was the first of the Five Good Emperors, and a bas relief bust of him will fit into the niche on the left side of my transom.

One thing that has occurred to me is that the center bust appears to use the image of Caesar Augustus as a template. I will use that image, but narrow the head slightly and combine it with the smaller mouths seen in the other two busts.
