If someone had the specs on the signals sent between the : caller id box and the telco I imagine that they could possibly invent a : spoof solution. Stipulated, anything can be hacked. The problem here is that, assuming you _haven't picked up the phone yet_, the design of the _switch_, _something the hacker cannot touch_, prohibits this particular hack. You can't get audio through the switch during the ring cycles. Period. Changing this requires rebuilding the line cards. Forcing the _switch_ to send bogus CNID is HIGHLY non-trivial as well.
