new game mode idea for a quick game

A fictitious game on summoners rift where you essentially pick up from a close game thats 40 minutes in or so. half the turrets are down everyone starts with like 11,000 gold .drag and baron don't spawn until 45mins 30 sec. (from starting time of 40 mins) or so. and everyone starts with 3 dragons and is level 13. and essentially only the back end of a game takes place. the last 10 to 20 minutes when its all about team fights etc get to nexus with everyone almost with full builds. for the first 45 seconds there is no fog of war to prevent cheese. everyone goes out to place wards during the first minutes, setting the stage. and start going for objectives mostly for those tired of farming for 15 mins with anticlimactic outcomes (dcs, tilts, total snowballs etc) . this would get straight to the late game full build part of the game.
