Different lock screen with Google Apps device policy

[Lockish]

Hi all,

I've been searching for an answer for two days now. Is there any way to use a 3rd party lock screen if I have Google Apps policy enabled?

I tried with a few from the play store: disabled stock lock screen, enabled the one from play store, added my work email(that requires the apps policy to be enabled) and when I had to choose a pin it always directed me to the stock lock screen.
