I mean, I'm not a theologist or anything, but based on other precedents, if someone was dying and wanted to be baptized at the last second, and no source of water could be arranged on time, the Gatorade baptism would probably be accepted by the Catholic church.
Transubstantiation of Gatorade into Holy Water doesn't even sound that outrageous when priests claim to transubstantiate wine to blood on a daily basis.
