Hahahaha right?! Unfortunately, there doesn't seem to be a mention of his awakening in the Wano OST but his theme sounds great so they may use that if it happens?:
I really wish we could have gotten "Awakened Kaidos Performance" unless Wano is gonna get a 2nd OST due to how massive it is and thus it will be on that one instead? Actually looking at the track listing, I think its all pre Onigashima so Onigashima will get a seperate OST hopefully or even Wano Part 2 OST and Kaidos potential awakening theme will be on that too?!
These are the tracks for the Wano OST so far anyway:
