This sounds great in theory, but one of the key issues with managing remote teams is there is no common time in the day that is "after lunch, end of day or first thing in the morning".
The reality is most remote scenarios require you adopt at least some async process; fighting this is a losing battle.
Some good news: your manager's job was always facilitate internally and protect externally; how this is accomplished has certainly changed but the core essence of management, if anything, is even more crystallized now.
