...Just a thought, if you want to increase action, instead of making such an enormus change, a secondary of the main team could be created (same name, emblem etc) with U18 players (16y, 17y,coming from our academies or separate TM) playing in friendlies or in a U18 separate league tto serve as a preparation stage (like real teams) and players can continue, as manager choose, to their carreer to the main team when passed 18y old. Thats would double the "action" and might be very addictive to managers.
