When structuring custody and support agreements it's not about looking "attractive"... it's about building the foundation for the LBS to create a new framework for his/her family minus the WAS.
There is no reason to wait to hear back and there is no longer any reason for you to sit around and wait for her to file something first. If you would like to change the arrangement and asked her in a reasonable fashion to work with you. If she does not respond or offer something in a timely manner then move up the chain of command.
Very well put.
Decide what you want based on what is good for the kids. What is good for your kids is good for you and WAS.
The cheapest and best path is to negotiate with WAS. If that fails, move to parenting coordinator, mediator, lawyers, then last resort judges.
