Based on what? Why would an equal split be any more or less confusing than alternate weekends?
Kids like routine. When I split up with my kids mother I was adamant that every other weekend wasnt enough and I wanted them more often. We agreed on Sat night - Tues they are with me, Tues night to Sat they are with her and they come round after school on Thursday, have dinner at mine and then I take them back to her.
We've been doing that for nearly five years and its worked really well. Splitting it like this has meant that theres no pressure to "do something" when they are round here.
We didnt get lawyers involved, but there were no joint assets involved. We started off by making a Parenting Plan (https://www.mygov.scot/parentingplan) which isnt really any more complicated than writing down what you've agreed.
I think the key things to remember are, kids are tougher than you think and will deal with the situation. It might not be easy for them, but they will be ok. And, as bad as things might seem now, they will get better
