I think that Luffy MAY get a stronger version of any haki, mostly observation/conquerors cause conquerors is Luffy's specialty?? ( I think i read that). Luffy is a battle genius, we know this because the crated his alternative of soru into gear 2nd with DF abilites. he saw Katakuris special devil fruit ability and his awakened moves, what if Luffy copies those and awakens his DF? (I think his DF awakening will be more affected on his body, he can move the rubber he is made out of to simulate Katakuris defense. This awakening also makes sense because the only two parcemia DFs that changes the human body into a completely new substance are the Gomu Gomu no mi and Mochi Mochi no mi, the big difference between these to devil fruits is that the Mochi fruit can generate Mochi. Another theory for luffys DF awakening will give him the ability to CREATE rubber just like Katakuris DF.) IF he did awaken DF he would still probably lose as Katakuri has more experience with the awakened DF. So he still needs a haki power up. Then luffy can probably beat Katakuri. This fits in as after the Reverire Arc there might be a Balitgo war arc... but then WANO. Luffy will fight Kaido... but Luffy is too weak currently!! He needs a power up soon! Lol will Luffy even beat him or he has to leave to his crew.
