I looked at adding occasional Twitch livestreams to my output but quickly realized to make it return any kind of sustainable income, you have to practically "become a streamer".
There's no slow on-ramp like with YouTube, where you could start earning income after a few weeks/months of producing content and promoting it, growing an audience.
And then if you want to pause YouTube for a month or two, you don't lose the metrics that allow you to have an income.
It seems like Twitch is a grind, a lot more so than YouTube (where there's enough pressure, thank you very much!), and unless you're fully devoted to it, or are single and/or young with a lot of time to burn (and very mature about how you burn it), it's going to be very hard to maintain any kind of work life balance.
