I doubt it. John was a nobody when Burke, DeSimone and Hill were doing their thing with the Vario crew. Burke wouldn't have given a fuck about Gotti unless he saw an opportunity to squeeze something out of him. Hill was always a bullshitter and not of the appropriate stock for a conversation with Gotti. DeSimone on the other hand...who the fuck knows? Guy was rambunctious, devoid of fear and nuttier than squirrel shit.
