If your plan is to physically move your head to look at the peripheral anyway, then this is much cheaper to achieve by putting a second monitor alongside your primary monitor (I keep an older 2560x1440 in portrait alongside my main 4k display)

Scenic gaming seems pretty niche outside of dedicated flight/driving sim setups? And regular gaming often kind of sucks on ultrawides - way too few games have decent options to pull the HUD into the center region of the display
