considering you've got all or most of the runes you need at the moment, I'd wait til the next free week and pretty try every character you don't own just so you don't waste any ip on "traps" unless you must have a character or something. You could also grab a rune page but considering you have no interest at runes atm, i doubt that is a good pickup. Also I don't think you need an AD carry considering you have sivir, ashe, corki and tristana which are all solid choices iirc.
