I could also see maybe:
$2, trash this, and set aside your Debt tokens until the end of your turn. (They do not prevent you from Buying cards or events while set aside.)
But yeah, best Looney Tunes reference in some time, and probably not that broken as is. Kind of cheesy for a one-shot, so idk, my first instinct is to water it down. Making the disguise only partially effective seems like one way of doing that.
