Ideas for Helping With Game Queues

I've noticed that, as a new player, it is hard to get into ques other than Summoner's Rift or Crystal Scar. I understand that these are the heart of the game, but finding groups for Twisted Treeline is difficult, and Howling Abyss is almost impossible to queue for. I've been told that once you reach level 30, there is more incentive to play other maps with a League, but it makes in hard for lower level players who want to do something different.

Perhaps adding a title or badge system for these maps would increase the number of players in them. Similar to the League ranks, this would just be an outline around your profile, or a badge on your account. Have various levels for each of the four maps, and one that is for finishing each of the titles.

This would give people more reason to queue for different maps, rather than just the 5v5 ones, and give newer players more diversity in playing, allowing them to fully experience the game and make them want to continue playing. This would make it much easier for people to make level 30, as they would not have to play the same map repeatedly.
