SP,
I can't speak for your fine state or your family situation, but when my XH decided the weekly plan sounded ideal, our mediator put a document in front of him that changed his mind. This was 12 years ago, so please forgive me for being a little rusty at this.
The basic premise is that if there was no separation or divorce, kids would have access to both parents intermittently (or jointly) all week long. I remember something about some psychologist's long term study on kids who were young when their parents divorced and were studied over 10-20 years. The results were pretty convincing. They felt disconnected and similar to pawns in a game. They felt that the needs of the parents exceed their need to access both parents equally.
My two cousins were victims of this set up. One is now a cop who turns his emotions off completely (he's a bomb squad technician and uses his extensive travel requirement to avoid conflicts at home), and his sister is now caring for their dad with Alzheimers. Their mom died a few years ago. She's in a generally happy marriage - she also married a child of divorced parents with a bitter divorce. But her H also travels extensively (nuclear scientist) and she's got a lot of anger left over from her childhood. Both of her parents have said at different times that they wish they had made different choices. They had the most acrimonious divorce of anyone I knew, and were in fact my role models in what NOT to do when my own D came to fruition.
And as I said earlier, my D20's teammate said that she felt her life had to be compartmentalized to please her parents. She had 2 separate lives with each of them and it really hurt her. She's a sweet girl (well, now young lady), but I'm not surprised that she has not had positive dating experiences either. She's 23 now, and is one of those people who doesn't trust at all. And that includes her parents. While she loves them both, I think she's pretty angry at how she and her brother had to grow up.
My girls were 5 and 8 when their dad left and when he proposed we go to the weekly schedule. My then 8 year old told her dad that she wanted to see both of us during the week. In the end, he agreed. It turns out that he only proposed it because he thought it sounded great not to have to parent for 7 days in a row.
I'd say if you are going this route, make it easier for the kids to be able to be in touch with their mom while they are with you and to ask her to reciprocate - for THEM. I can promise you that my XH would sure as hell not wait 7 days if one of them started their period on his watch. Or if it was spring break and 3 doctors appointments were set up and it fell in his week.
