I imagine Katakuri could do something similar to counter it since he did with elephant gunGear 4 is kind of a question mark right now. As it stands, Katakuri technically couldn't replicate it due to the different properties between rubber and mochi. But while Luffy could use it, there's no guarantee he would be able to get a hit in. And if he does use it then he risks the stamina drain.
It's clear Gear 4 is going to come up, but it's hard to see what difference it could make.
