The only reason this would be a hail Mary would be if you have a cynical (and correct) view of the conservative majority of the supreme court that they are willing to completely debase themselves and the law in order to get a desired outcome. The law clearly states that the president can "waive or modify" any provision of the federal student loan program. Justice Roberts argues that forgiving some student loans is not waiving or modifying provisions, it is rewriting it from the ground up. Which I don't think any honest assessor would agree with. You could literally add one line to the existing provisions to accomplish the loan forgiveness. But more importantly, you must have standing to bring a lawsuit and this was one of the weakest cases the court has ever approved for standing (possibly with the exception of the 303 creative case) because there was zero evidence of harm to the plaintiff.
