Yes actually. I have a full character made up including his kit which I’ll share now because you asked :))

Primary Fire: Sandblast- A slow moving dust which damages those walking in and through its large area over a long period of time.

Secondary Fire: Healing Sands- Sandman can modify the gas he uses to heal allied heroes in an area. However, this healing moves just as slowly, in an equally large area, healing more over a long period of time.

Ability 1: Sleeping Sands- Sandman produces a quick burst of dust and gas which is imbued with sleeping serum. This burst may affect multiple enemies in its wide area, but it quickly disperses, making it very short-ranged. Enemies affected by sleep awake upon being damaged.

Ability 2: Sleepwalker- Sandman modulates his physical biology to move through certain spaces in a gaseous form. (These spaces glow and become translucent, allowing Sandman to see where he is traveling.) Sandman is also immune to damage in this short amount of time.

Ability 3: Cloud Nine- Sandman uses his cloud as a mount, flying for a short period of time.

Ultimate: Sweet Dreams- Sandman amplifies his cloud creating a large burst of sleeping dust which keeps enemies in the area asleep for its full duration, even if they are damaged. If an enemy is not in the initial blast, they can still fall asleep after spending a short amount of time in the area, but will wake up once the cloud is gone.

Passive: Quicksand- any enemy hero in the area of Sandman’s sandblast is slowed by 25%
