Using Majority Class to Predict Minority Class
Yes that's correct, but assuming that you follow the exact same methodology you will obtain exactly the same performance at the end, so there's no advantage.

Keep in mind that the problem with class imbalance is not that one class is harder to identify than the other, but rather that it's harder to properly separate the two classes.

[edit] It would be a different story when using one-class classification. I'm not sure if it makes sense in this case but maybe it could be something worth trying.
