There might be a way - on Android apps can have a lot more permissions than what iPhones allow, which can allow for some pretty cool things. This app is the first similar one I say in the Play Store, and can sortof do what you're asking. Basically it replaces the default lock screen. The way this one in particular works is based off gestures - when setting it up you determine a gesture that will unlock your phone. If you find a picture of a 4x4 or 5x5 grid, you could set that as your lock screen background.
I can't personally vouch for the app I linked, but with 4.3 stars it probably isn't a POS.
Maybe a lock screen app like this https://play.google.com/store/apps/details?id=qlocker.gesture
