Default [Q] LG G Flex Lockscreen

Hi everyone, I've searched and seen some ROMs that can support the LG G Flex lockscreens but I was wondering if there was any other method to doing so on the stock LG G2 ROM? If anyone knows please let me know. I also saw that the G2 Tweakbox module has a feature to enable the LG G Flex lockscreen theme but I was wondering if it worked like the original.. if anyone has the premium version and has pics or videos of it working, a reply would be greatly apprectiated. Thanks in advance!
