Livestreaming to Youtube and simultaneous interpreting

Hi everyone! 

Hope someone can help me. I understand it is not possible to set up the livestream to different youtube links according to different language channels within the same webinar, since the audio that is captured and livestreamed is the original one. Now, is there currently any alternative to this, so that webinars with simultaneous interpreting can be streamed live?

If there isn't should I invite the portion of the public that I know will need the translation to be in the webinar and use the tool, while still livestreaming to youtube for a wider audience? 

Thanks!
