Doesnt matter at what weight the fight would be set at Ray would still beat Joe. Take for instance the Joey Maxim fight Ray lost , he was fighting at 158? 157? and winning the fight , but lost to heat exhuastion. Maxim had previously fought for a world title at Heavyweight. Ray does everything Joe does , but way way better in a one sided miss match at anyweight Joe wants , and he can bring his dad in as well.
Ray also walked on water and turned water in to wine. I also know he flew using his junior birdman rocket pants and single handedly brought Apollo 11 back to earth but as far as I am aware that's still classified so keep it quiet ok.
