Can I have a folder (on the home screen) with more than the default amount allowed per folder on the Nexus 5, which is 16?

I'm searching a way to make all my games into a single folder. Is there a tweak/app/root command to makes my folders (not storage folders, folders in which you can add shortcuts for apps n' stuff) have, for exemple, multiple pages, kinda like in the IOS system, or a scroll-able folder? Or a way of having a folder in a folder (which would be overkill but hey, it's still a way to enhance the capacity of the folders.)? I'm using a Nexus 5 running the stock ROM with Android 5.1.1. *And I would prefer staying like that, not using Launchers or custom ROMs.* Thanks! ^.^
