I think the first teaming up will fail, but once marco, drake, and hawkins get up there and replace zoro/killer, and hawkins uses his abilioty to bolster them, if not ALL of the allies on the island, drake starts pulling out awakening, marco pulls out awakening, law starts creatively teleporting allies around for free hits and landing hax moves if he can/teleporting objects and attacks around, marco starts using his flames (maybe as a coat of armor on all the heroes so that all homies can't touch them and are repelled), Luffy can start landing hits thanks to his increased support, Kid puts more pennies in his pillow, etc, we will start to see some results.
Also in greek mythology, the moirai tricked typhon and made him eat an ethermal or whatever fruit, which weakened typhon, promising it'd give him power.
Moirai = the fates, who use strings
Typhon = king/father of monsters, which is who kaidou is
Typhon will be weakened by doflamingo's fruits, which is another of doflamingo's tricks, it will backfire, and that will allow the alliance to pull a narrow victoyr.
