Would it be possible to have a "First Win of the Day" for all Modes instead of just one?

This is something I was just curious about, but would it be possible to give all modes a "First Win of the Day" bonus instead of every player having only one per day?

The mechanics could largely remain the same (player plays a mode, gets First Win, First Win for that mode is put on a 24 hour timer), but now players would have more incentive to play different modes along with a way to gain some more IP quickly.

Its just that right now I feel that the current IP Gain is a little too low, especially for people still buying Champions who can't play for more than a few hours a day, making buying Champions who cost 3150 IP or more take like a week, maybe longer if you're unlucky with your wins.
