I'd take a leaf from the current idea some areas are going (womens tri series and county/WSL) I'd have 2 games scheduled on a day, home team plays twice. It'd be 80 overs in the day so less than players currently play and would free up more days in the schedule.
16 year old Will Smeed his 116 for the 2nd XI, trescothick also hit a ton, just a 26 year age gap. Coached a junior team a few years ago and Smeed was in the opposition, looked a quality player back then even at the age of 11.
