That last statement tracks with the OP fine, but we'd sort of moved onto "how much of a threat would she be." And there, well, she just isn't one to the heavy hitters. Which ones qualify for that status? Obviously Goku, Veggie, Frieza, MVP17, Jiren, Toppo, Kefla, Hit and Beserk Kale. Hell, Roshi might well be able to Mafuba her, given that it worked on SSB Veggie.
Hakai might work on her just fine - given that it was explicitly stated to work just fine across timelines and multiverses and everything else. The only thing that stopped it from properly functioning on Zamasu was the Super Dragon Balls and the specific wish to protect themselves from that. But you are correct, that would be a DQ for the character that did it. Given the threat level, however, a self-DQ to take out an otherwise unbeatable threat seems like a pretty good idea, and someone like Toppo would probably do it.
