Can you stack Aonson top of each other?

[JustQuestin2004]

I was thinking about a little quirk about the Aons I saw form the page on the Coppermind:

Spoiler

Aons can only be destroyed by an Elantrian. Unless destroyed by an Elantrian an Aon will continue to function even if it is scuffed or erased

So if you drew an Aon in the dirt with stick, then rubbed it away, then wrote another Aon exactly where the first one was, what will happen?

Will both Aons work? Will they interfere with each other?

There's not a whole lot of context for this yet, but since Elantris shows "linked Aons" as well as "Aon Modifiers" I think there are a couple possible outcomes. (it would also depend on if the first Aon was already "activated" and drawing upon the Dor or not)

1. The First Aon is "activated" and creating an effect that does not affect the drawn Aon[1]. The Second Aon may be possible in the same physical medium as long as it is an unrelated affect or is "linked" to the first Aon.
2. The First Aon is "activated" and creating an effect that does affect the drawn Aon. Since the first Aon will have "changed"[2], the medium is likely now "empty" as far as the Second Aon is concerned."
3. The First Aon is not "complete" or activated. The second Aon would likely interfere because it would be like "extra" or "incorrect" lines in the first Aon, causing it to be invalidated

1: A longer-lasting effect (like Ashe) would produce a continuous effect until "turned off. Elantris Ch 7, 55

“Ah, sule,” Galladon said with a shake of his head. “You still don’t understand, do you? This is Elantris, city of the gods. What need have gods of such mundane things as lamps and oil? Look at the wall beside you.”

Raoden turned. There was a metal plate hanging there. Though it was tarnished with time, Raoden could still make out the shape etched into its surface—Aon Ashe, the character he had drawn just a few moments ago.

“Those plates used to glow more brightly and steadily than any lamp, sule,” Galladon explained. “The Elantrians could shut them off with a bare brush of their fingers. Elantris didn’t need oil—it had a far more reliable source of light. For the same reason, you won’t find coal—or even furnaces—in Elantris, just as there is only the one well. Without AonDor, this city is barely fit to be inhabited.”

“It’s too far,” Sarene said. “Where is Ashe?”

Raoden reached up and sketched Aon Nae—a large circular character—in the air before them. When he was finished, the air inside Aon Nae’s circle rippled like water, then cleared to show a magnified view of the city. Placing his palm in the center of the circle, Raoden maneuvered the Aon until it was pointing at the palace. The view unblurred itself, and they were able to see the soldiers with such detail that they could read their rank insignias.

The Aons are turned off by touching them and willing (Commanding?) their effect to end.

2: However, some Aon effects warp and change the drawn Aon when creating the effect. Elantris Ch 49

He rushed over to his stack of AonDor books, selecting a large volume that contained nothing but page after page of Aon diagrams. Galladon, whom he had left behind midsentence, followed with a grumpy expression, peeking over Raoden’s shoulder at the page Raoden chose.

The Aon was extensive and complex. Raoden had to take several steps to the side as he drew it, the modifications and stipulations going far beyond the central Aon. His arm ached by the time he had finished, and the construction hung in the air like a wall of glowing lines. Then it began to gleam, and the sheet of inscriptions twisted, turning and wrapping around Raoden. Galladon yelped in surprise at the suddenly bright light.

In a few seconds, the light vanished. Raoden could tell from the startled look on Galladon’s face that he had been successful.
