The developer behind iCleaner has his own repo. On his repo he has a tweak called No Slider Text. I'm not sure if this is what you're looking for but the description says it:
Removes "swipe to unlock", "swipe to shutdown", "swipe to answer" and more swipe texts.
I've never tried it and I'm not sure if there are different options where you can select which slider texts you want to remove but it's worth a shot. I'm a fan of his stuff. iCleaner is pretty impressive for everything that it does. Check it out and let me know how it goes. PM me if you need the repo.
