I love Kodi and think LibreELEC is great! So there is no misunderstanding about that =)
But, the LiveTV of Kodi is not mature enough for me. I have for the last 6 months done everything I can to try to adapt Kodi to the way I want to use LiveTV. But there is simple some features missing and bugs left. And since I'm not a developer, and the people that are taking care of LiveTV in Kodi can't do everything immediately, I'm thinking of going back to MythTV frontend. The frontend is not perfect, but it has the basic LiveTV features that I need and use. I'm sure that Kodi will get there eventually too.
Anyway, now to my question. Since I want to continue to use Kodi for movies/series I would like to have MythTV frontend on the same Raspberry Pi3 that I use today. But is it possible to install the frontend on LibreELEC? Or is LibreELEC so streamlined for Kodi that there will just be to much work to get them two to live together?
