Okay, so I just make Lowen look, act, and perform like Leila, but not be her. Thanks.
I still am figuring out how the heck to edit the prologue in FE8, and I can't Event Edit yet.
EDIT: This is totally unrelated to hacking but, my Visual Boy advance crashes on every patched game I have tried. The exception is dream of five. I have also tried other emulators, but these crash too. Do I need an older version of an emulator?
