Would be pretty easy, once you got the soft sultry voice to say those words

1) Record hot chick sayng your words of choice
2) Use sox to convert to 44100hz 16bit stereo RAW format (
sox hotchick.wav -r 44100 -w -c 2 hotchick.raw
)
3) Rename hotchick.raw to hotchick.pcm (for consistency)
4) Upload hotchick.pcm to /drive0/var/tts
5) Modify /drive0/var/ttsclock similar to how the strongbad modification was made: 
greeting="${ttsdir}greetings.pcm ${greeting}"
