It's a complicated answer, but yes and no. A pilot needs to warm up in order to pull the high Gs as rated by the airframe. In addition, you can only pull the rated G-force for the plane for so long before blacking out. In addition, the plane has to be re-certified after going over a certain G rating.
I recall hearing that yes, they could, but it will wear out the airframe faster. Like all engineering projects, they are designed within constraints. Of course this is frame dependent, but it also means new airframes designed without pilots in mind are now possible.
We often see green flames shooting across the sky without descending in SA near the Woomera test facility. I put it down to boronated fuel, but most people put it down to meteors with high nickel iron or copper content.
If only there was KolourPaint for macOS. Recently switched to Mac and I really miss simple editor for quick editing (crop image, add another one, add text... in short: making low-effort memes).
Upd: looks like it might be possible in the future [1]
If you see the human being as a vehicle for a soul then this sort of manipulation can have a counterpoint.
