Can Android Launchers change multi tasking menu?

This may seem like a noob question but I like the multitasking menu view in Android L but since my phone probably wont be updated to Android L I just wanted to know whether it is possible for launchers to bring this view to older devices?

I don't believe a launcher can. But I wouldn't be surprised if there was a method using xposed or something. I wanted the lollipop look on my phone so I loaded an unofficial cm12 build.
