A suggestion, but when you've got the free time, you should look into doing multipart streams about cows you've been wanting to talk about for awhile, but haven't due to the sheer amount of history some of them have requiring a DTRH-esque documentary to do. Something like the Tooter stream you did last year, where you brought on quite a few guests who were more knowledgeable about the subject at hand.
Would require quite a bit of work to set up, research, writing some kind of basic script outline (like some kind of rough timeline, notes, jokes, et al), getting schedules together, etc, but a lot of people would enjoy it.
Also maybe look into building some cheap ass DIY acoustic treatment you can easily move so you can cut down on the echo when recording. It personally doesn't bother me, but I'm aware there's a not insignificant number of listeners who bring it up. You could probably pay a fellow borscht addict like 50 rubles to put it together if you find a cheap enough solution.
