Any hope for doing the Amazon Position with a BBW?

My girlfriend recently told me that her favorite thing to watch in porn was the Amazon position. I would happily try this with her even though it’s looks very intimidating for the male, but we both had concerns over her weight (5’6” around 250lbs) making it unpractical. Id feel really bad if we cant make this work, has anyone been able to do something like this and can share some advice?
