I tried to do a low level run for the early game of FF6 til I got my espers so I could get extra stats on my level ups. Ipooh was fun to figure out cause it seemed not doable, but finding some extra relics and remembering that everyone could go on back row helped a lot.
(I had to do it three times cause Sabin kept dying in the solo battle, lol)

Had to quit at Ultros though, he kills everybody in one hit and they hand you Banon who is an instant game over if he dies.

Plenty have done it, but I want to get through the early game without going crazy, lol
