I think it's a good answer with the potential to help the OP. It seems to be well-reasoned, and although implausible, the scenario you provide still fits the given circumstances.
I get that downvotes are discouraging, but that doesn't necessarily mean it's a bad answer. The answer's mixed reception probably came from the fact that a lopsided body is by definition not a planet - making the post appear not to be an answer. I disagree with this perspective. Such a technicality won't prevent the OP from achieving the desired effect. Plus, the question isn't tagged with "science-based" (though it's arguably implied by the "orbital-mechanics" tag) so any relatively logical answer, imo, is valid.
In the future, it could be helpful to acknowledge such a technicality in the body of the question when it comes up so it becomes a deliberate concession / rebuttal, rather than an apparent hole in your reasoning.
