As far as the list goes, if she agrees enthusiastically to placing time and dates on requests from each other is there any potential issues you see?

The only problem I see with this is that this places the responsibility for ordering your schedule on your wife's head and not yours. You know what all things you need to get done on the weekend. There may be additionally things that she doesn't know about (who knows, wash your hair, research something, etc).

As long as you POJA this it shouldn't be a big issue.

My husband is very sensitive to the sense that I am running his free time. Therefore I'm not very positive about specifying when I want something specificially to be done. I can tell you that if I ask DH to do something, and give a time, and he agrees to it, and he doesn't follow through...that is a LB.
