I'm reading her playstale speculation and inspirations again, and while it may sound unclear in general there are some interesting points:
"Aeon’s attack themes may be similar to Double’s in that she wields hypothetical versions of characters to attack, conjured from the distorted reflections on her hourglass. She may use figures from the past, characters that have not been seen yet, and alternate versions of the cast including ones where they have become the next Skullgirl."
Well, one of her inspirations is Double. The last bit is interesting since we now have Skullgirl Umbrella (palette+voice pack) ^_^
To differentiate this from Double, I guess these figures could use skull projectiles, shadows and other stuff similar to what Marie has.
"Her own attacks would be themed after sand, glass, and Khronos’s serpentine incarnation with animations that don’t always flow forward."
MK11 didn't exist back in 2013 but after reading this I believe Geras could be a perfect inspiration for her gameplay.
Sand and time manipulation!
He can do some pretty crazy combos.
"She may be able to capture moments on the battlefield to unleash later, like a bubble in time containing all attacks executed within its bounds."
Now this sounds very complex, but I think something similar can be done by taking inspiration from both Geras and Bedman.
I can see it working as a mix of Deja Vu/Tasks (Bedman) and stuff like Reverse Time/Stepping it Back (Geras)
"Then there is the usual slew of abilities to consider like rewinding time, slowing it down, and stopping it."
Izanami:

Just like with Isaac's inspirations, I don't know about Dio Brando and Sakuya Izayoi lol
I think Aeon's playstyle sounded more ambiguous than Isaac's due to some of her inspirations being Omega Tom Hanks and general things like Super Time Force, Prince of Persia, Hounds of Tindalos, etc. where it's not very clear exactly what elements would be taken from them to apply on her own gameplay.
But if I think "ok, this character plays like a mix of Double, Bedman, Geras and Izanami", I can see it more clearly.
The thing is... I think these characters didn't exist back then when we were voting for the DLC characters.
Geras (MK11 - 2019)
Bedman (Guilty Gear Xrd - 2014 onwards)
Izanami (BlazBlue Central Fiction - 2015)
We could say Aeon was ahead of her time
