OMZ is part of ichigo's zanpakuto so i don't think that Yhwach can reclaim it because he can't steal zanpakutos and only bankais(i forgot ichigo had already activated his bankai so this is possible).Maybe OMZ can do something about it because he and Yhwach are the same person but at the same time they are not.
