I don't think that Yhwach now has those dead guys powers. I think that his power gave others powers based on their personalities or such. After all, Mask was most definitely a Superstar, even without the power of it. He was given a power that was essentially his personality turned into a weapon. Same with others as well. Bazz-B is a hot head, so he can use fire. The Lloyd's were always capable of imitating people, they just were made to be capable of making it more realistic. So when these people die, Yhwach would likely just be getting a matured piece of his soul back, making himself stronger.
