Do you guys think league Would work with shorter match times?

I would love to see shorter games 15-25 min games instead of 30-45 min some times 50+ min, games become a drag i still love league but it is becoming increasingly difficult to play , So i am asking this would it be possible for league to have shorter matches and still feel like league?? Hots has nailed it with their match times.
What do you think would have to change for this to happen?? My opinion is more objectives to do on the map for pushing towers but i cannot think of way for this to happen without changing the entire map.

People live busy lives now days.

in 3 hours of league you can play mby 2-3 games depending on match in hots you can play twice that on average which means more fun for us playing league. Twice the fun.
