My husband pointed out that another option available with a solo 401k that is not often available via employer-sponsored plans is the ability to set up a Roth 401k. My understanding is this would allow for much higher Roth contributions compared to a Roth IRA.

Also a bit risky depending on your exit strategy and the assest recovery mechanism.
Not going lie either... this is generally the type of behavior that gives these programs a bad name and creates pushes for reforms - using them them to FIRE while maxing out the 401k. Most people are fine with assisting the needy through these types of programs. The support for these programs completely changes when given situations like this. Especially when knowing the over a third of the state budget is used for this program and that my own medical care is more expensive due to provider taxes to help cover it.
