Sure, it should. What prevents you from implementing it as:
NotANumber>>+ number
^ self
NotANumber>>adaptToNumber: rcvr andSend: selector
selector == #+ ifTrue:[^self].
selector == #* ifTrue:[^self ].
selector == #- ifTrue:[^self ].
selector == #/ ifTrue:[^self].
^super adaptToNumber: rcvr andSend: selector
and so on..
