Voice variations are definitely an issue with the so-called "modern
voices".

1. In my experience, using completely different voices, vs variations
   on a voice is too distracting.
2. I've compared  that  in the past to the "ransom note phenomenon"
   where one uses glyphs from different fonts on the same page.
3. needless to say, the above is known to be distracting in the visual world.
4. Switching voices like that mid-stream will also break intonation
   and likely add latency.
5. Piper (neural-net synthesis ) has "multi-voice models" but they
   tehmselves acknowledge that this reduces quality.

   But all in all I'm really glad to see you investigating this issue
   -- rather than getting stuck in issues of setup.
