Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
You can target 2 Level 6 or lower monsters with the same name on the field; their Levels are doubled. At the start of the Battle Phase: You can target 1 "Cipher" monster you control; choose 1 other face-up monster on the field, and its name becomes that "Cipher" monster's, until the End Phase. You can only use each effect of "Double Exposure" once per turn.
