Yes that would mean that...
People saying "Abc logic" doesn't work, probably aren't reading one piece or shounen mangas.
Here's the problem though....
Doflamingo has had to fight the following people: Law, Luffy, even to a degree Fujitora. Whatever shape Luffy leaves Doflamingo in it won't be 100% which means the Doflamingo Zoro beats isn't the Doflamingo Luffy fought.
Just look at Naruto vs Pain... Would Naruto beat Pain if pain had all paths at 100%... The second Deva came back Naruto got wrecked. It took a loss of control due to Hinata to get him saved.... Are you saying SM Naruto > Nagato?! He really isn't.
One on one there isn't a SH or Heart pirate that bests Doflamingo Doflamingo. Which is why Law is fighting him. He will probably be weakened to the point to where Luffy stands a chance.
Luffy has speed and intense armament Haki (not to mention a fire attack of his own). IMO the only technique that'll stop Luffy is the strings... Which are plausibly burnable: thus Luffy had to catch on fire completely (gear second and a full body armament Haki).
But yeah no one in the SH crew has a shot at soloing a full powered Doflamingo right now.
