I'm honestly wondering how the NHL (and especially the owners, who seem to be involved in thoughts like that) got the idea that the olympic community has to cater to them? Do they think hockey fans and hockey organizations around the world are blaming the IOC for games without NHL players? Let me give you a hint: no, not at all. Either they blame the NHL or they don't care, which is understandable as suddenly the playing field is more even. In the near future I don't see why the IOC would reach out to the NHL in any form. And, as others have said, the next games are already planned, and usually there are no ice rinks involved.
Don't get me wrong: The IOC is an even more dubious organization than the NHL, but that doesn't give the NHL any right to demand stuff like that. Hockey is an integral part of the winter olympics, and it would hurt the winter games a lot more than it would benefit the summer games, if there would be a benefit at all. In summer, hockey would just be one minor sport with huge costs, in winter, it's one of the highlights. Why would the IOC change that?
