But, then once the season is over, he will have OW out there for 2 weeks to make him feel better. Maybe, doing the whole Christmas thing to the hilt may make him think about family, your daughter, while with OW, and what he is really giving up.
Difficult choice to make, and maybe he will say no, anyway. If you do invite him for Christmas eve or day, then make him understand it's for D's sake. While at the same time, you make sure you are dressed scrumptiously Christmassy, have his fave holiday food, and make the gift opening fun and enjoyable. I would even have photos of happy Christmas pasts situated around the house, especially ones with D and H together. If you have other people there who he loves and respects, even better. Less stress for you to keep convo up.
This is more of a reminder to him of what he is losing, and a contrast between you and OW ... balance it in your favour ... than if he did not attend. Just a thought.
