I propose that your character's name not work as an alias to target you with when you're disguised, and you're instead given the option to set an 'alias' when you disguise yourself.
You bunch up the matte black poncho, and fit your head into its hood, before relaxing your grip, letting its fabric drape down over your body, adjusting its fit with a slight tug here and there.
[Please enter an optional alias for you to be referred to. One line of input, @abort to abort.]
Okay, you are now targetable by your shortdesc keywords (a shrouded squat mano) or the alias 'Catmother'.
If your disguise breaks/is removed, you don't have the alias anymore and you're targetable as normal.
