Enchanter illusions and faction

[ssyrax82]

Lets say I want to hunt Dark Elf guards, as a dark elf... If I were to illusion myself to High Elf to lower my faction, would I bottom out sooner? And then would I stop taking faction hits because I am bottomed out so that when I switched back to my Dark Elf self my faction hit in the end was not so large? Does anyone know?

This is just an example, as I am not a Dark Elf...
