Probably for live but not for everything I want it to have. 4K 50p, 10bit for example. For live it will be B or C-camera, same goes for doc/news/video shooting + photo camera (BTS + photographs). So its close but not there. As a live only, it would probably be more than enough.I can say, I personally use an RP for this very purpose you mention here. I broadcast with it for 4 hours at a time, no problem. Might be a solution for you.
Right now I only have a XA50 which does everything except bigger sensor. It has XLR, good battery life (but I do want BPA on a Cine camera for dtap + usb), 4x bigger sensor than the xa20 etc, easy to rig up. Also it has a good grip for shooting, and 4k 25p. What it lacks is the "cinematic" parts, which I hope the C50 will give me.
A little note: I am in the beginning of my career, have done 2 years of media and communication, and I am going to take a bachelor in tv production (education here is free and super connected to the world). I mostly work freelance as a camera operator, but I also do my own projects and other stuff with my gear. Been doing live for about two years.
