I agree, there is enough evidence to question his fate. They've never directly stated he was killed (just "obtained/captured"), and we don't know enough about the process of creating Quinque to know whether it would be possible to continue making Quinque from a single Ghoul nearly a decade after their death (or how many they can produce from a single ghoul).

We DO, however, know that it is possible to extract the kakuhou without killing the Ghoul. And they will eventually regenerate it, as long as they've got more than one as a Kakuja would.
