Gear 5th

So i was thinking and of course the manga is not still in the middle of it's story so probably there is going to be a 5th gear and that would be related with the awakening of the fruit gomu gomu no mi, as we have seen mingo's awakening was transforming the city into strings but Luffy was able to manage dodging them and use the Lion Bazooka, but what do u think if Luffy transformed his surrondings into rubber so he could jump, run or attack more effectly? And... Just maybe he could emerge on the rubber, like a zoan type? Thats just a theory but lets see Next topic will be dressrosa bounties and next crewmate See u soon, Deo Umis
