[MCU] Are there any wishes that use all the infinity stones that wouldn't leave you hurt/Scarred or on the brink of death?

Potentially yeah. 

The reason the stones do so much damage (aside from releasing a ludicrous amount of gamma radiation apparently) is that you're not making a *wish* so much as you are performing an action that draws on the Stones' powers. 

The bigger the task, the more power you draw from the stones, and mortal bodies can only take so much of that power surge. Destroying Thanos and his forces was enough to kill Stark, but Thanos could withstand wiping out half of the life in the universe, even though it significantly messed him up. 

Thanos could probably snap a planet and be fine, or certainly a city or something. The power that would require would be insignificant to the power he tanked in *Infinity War*, while still using all the stones.
