I would personally be really interested in seeing this since I've thought a lot about a TTS plugin (but I'm not very interested in the details of TTS). One of the uses could be to read subtitles aloud. Another could be to sing the lyrics of a MIDI-file (if it also accepts one of the MIDI-channels for frequency).

I do not think you should make any source or sink elements, I think it would be better if other elements took care of that. Like this:
textsrc ! voice ! throat ! tongue ! lips ! audiosink

Honestly I don't see the need of making four separate elements, but I guess that's because I don't know about the details of TTS. Some alternative solutions that pop in in my head:
... ! tts sex=female throat=husky ! ...
... ! female_voice ! husky_throat ! tongue ! lips ! ...
