I am not sure where you live, but I just went through this with my lawyer on my separation agreement. Essentially, he said that there is no set plan and that whatever you both can agree to will work. If you can't agree then it will go to court.
At a minimum, he said I could expect the kids to be with their dad every other weekend and Wednesday evenings as that is the basic expected custody agreement. (This just happens to be what we agreed to.) He also said that if the kids have activities those evenings that the STBXH would be expected to take them as my son has tutoring on Wednesdays.
It sounds like your WH wouldn't put up much of a fight if you went that route. Also, my lawyer said that if the kids were teenagers that they would be able to tell the judge how often and how they would want to see their father.
Not sure if that helps, but it cost me $350 p/hour so I thought I would share and maybe save you some money.
