Ranked League Names

Just an idea, but what if we had an option to reroll our Ranked League names in the store for a nominal fee (purchasable with IP as well). There could be a relatively cheaper, completely random option. The other option would allow you to choose a specific Champion to represent. However you must "unlock" a Champion via the Champion Mastery system before you can choose them. (Tier V or future Tier VI reward?) Yes yes I realize this does absolutely nothing, but still.. Just got placed into "Pantheon's Archons" and I don't even own Pantheon. Thought it'd be neat to be able to be in a League with my favorite Champion ("Lulu's Guardians" please!), rather than a random one.
