I am convinced that he will be. He has two valuable bargaining chips: Garp and Caribou. Due to Crossguild, the navy lost alot of prestige. The World Government will try to prevent any more humiliation. Caribou can store unlimited food inside of himself, and thus can end the food shortage in the Holy Land. Those two will easily buy Blackbeard a seat at the table of the Revery.
He has betrayed the Government before, but making him king is not going to make him any stronger. He can attack the WG with or without title.
