This has been a question asked when the N5 came out. I don't think anyone has pulled the dialer apk from the N5. I was disappointed when I realized that feature wasn't present after the kit kat update. Perhaps it's an exclusive feature of the N5. I've been using "contakts" for my dialer and contact list and have been happy with it. I love the translucency provided by 4.4 and its GUI. Here's the play link : https://play.google.com/store/apps/d...whney.contakts
I used the file manager inside of safestrap to install the apk in /system/priv-app, then changed permissions with chmod 755. There is an app in the play store called QuickShortcutMaker that allows you to create a widget of any activity. This means that you don't have to use Nova launcher to launch the Google dialer.
