Rune pages 20 is not enough

So I have been playing League of Legends for years now buying all the champions and runes. I have built countless mastery pages and rune pages throughout all the changes with the game. The question I have is this do you ever plan to allow for more than 20 rune pages? I am certain this is more than enough for most people but seeing as I have been playing since some point in season 2 whenever Nautilus came out I have had enough time to buy all the runes... well almost all of them still need 2 Energy Regen quints. If it was ever a feature you guys had mulled around with I would love to see it implemented. I think the reason I would enjoy it so much is because I enjoying customizing every aspect about the playstyle I have for a champion and I will generally make a rune page and a mastery page for them before playing them.
