I might, although I think the Hasselblad will be a better choice.
What works for you is the better choice.
Some people seem to be confusing "protest" with "riot". A protest is mostly static: people moving slowly, people standing and not moving at all, people sitting. You look at Ta Mwe's photos you mentioned, that's exactly what you see.
In other words, you could easily and perfectly photograph a protest with a hand-held 4x5, if that's the camera you're used to, you're comfortable with, you know how to use to its advantages and understand its disadvantages, and which corresponds to your vision.
Furthermore, what's interesting, photographically speaking, about a protest is not the crowd — unless you want to show how huge the crowd is, in which case what you need is distance —, but the actions and expressions of individuals or small groups. So what you need is something that can take you close. That could be your feet — in which case you take a medium wide-angle lens corresponding to the format (35mm, 120, 4x5, etc.) you chose —, or it can be the lens, in which case you just carry around telephoto lenses.
If you don't have a choice, as in the Koudelka example I mentioned, then you adjust to what you have and make it work according both to what you see and how it can be translated photographically. That's why a question like "should I use a 60mm lens with a Hasselblad?" is absurd. Only relevant question is "I have a medium format camera and a 60mm lens, what can I do with it, what's the full range of it's possibilities, and how can I adjust to them and learn to master them?"
That said, in the end, you might realize that such or such camera with such and such lens doesn't work for you. Sadly, only after the fact. But if you took the time to understand and master the tool you have in combination with your photographic craft and skills, chances are that might not happen.
If I were you I would stop looking at options. There will always be options. Options don't make you move forward.
What will make you move forward is showing photographs and requesting critique. No one can answer the question "Should I use a 60mm lens?". But one can say after looking at a photo: "I understand what you're looking for, but if you're going to use the 60mm for this type of shot, you need to move closer." Just an example. But that, to me, is the most relevant way to talk, and learn, about gear.

P.S. I don't know if there is a 60mm lens for the Hasselblad, but doesn't matter, you get my drift.
