I think it's pretty well documented that Capone was friendly with guys such as Lucky Luciano (there is legit footage of them together in their younger days). Taking out Masseria and Maranzano was a way of taking out the old guard to make LCN more of an intertwined across the country and was instrumental in forming the commission. I feel like Capone and maybe some other top guys in Chicago at the time were made aware of the plans, as it played a key role in Chicago being intertwined with the other 5 families for the next 5-6 decades. This is just my opinion.
