So there could be a character with a different name that was a Mabel clone, for example.

This has caused some confusion. The theory is that Lebam is just the clue to the backwards nature. I think there's a second version of Gravity Falls happening on screen and they're near identical.

It's often assumed that I'm saying the girl's name is Lebam. Her name would be Mabel just the same as her doppelganger except she'd be backwards. (Much like what would happen in our reality if one were to traverse a Mobius strip.)

Let's also consider Hirsch's statement "Mabel's a ham" is likely related to this theory.
