I know that I'm not in any place to be giving advice, being new to this and all, but I think that since she has never really had a close relationship with her father, if you send that and it does get back to her, she might think you guys are ganging up on her. Not sure what her state of mind is where he is concerned.
Here's what I think, just my opinion. I wouldn't send anything out unless you'd be okay with her reading it personally. If she read that, would it help or hinder your goal of reviving your marriage. What if he gave it to her, he probably wouldn't, but could you imagine?
I know it's hard, but if you really want to send something asking for his support I'd mention only the positive. How you love her and still want your M. How you'd love to resume C with her. How you'll keep working on it... I don't know about the other stuff tho!
Good Luck.
