How to use/install Xperia lock-screen on any Android?
After doing some extra research (5 or so sec), I found that there's an app that gets close. It's called XZ Locker. You can get it from the Play Store.

It has what I asked for.

Pros:
*Very flexible in controlling what elements show up on the screen.
*Let's you customize many aspects of the look and feel of the elements on the screen (e.g. font-size/color, swipe animation, etc.)
*Lightweight and allows for additional options some implementations don't have natively

Cons:
*Security isn't the best. It allows for a maximum pin number of 6 digits. If that isn't chosen, then it gives the option of a defined sequence of gestures using the common dots on the screen.
*Kind of buggy. Certain things create a weird behavior on the app, but not the representation itself (e.g. extra app instance when testing screen).*Can be slow at times, depending on app usage and etc.
