I have no idea what project you work on, but that sounds like 30 different teams each experiencing:
1. Rare actual urgent issues
2. Shit leadership adding last minute requirements (that no scrum or waterfall or agile whatever would help with)
3. A bunch of config changes (I worked on payments systems in the past. We had some contractors who would basically mess with config files all day as countries changed laws, etc).
4. Stuff that only quant firms care about
Regardless, you didn't address the second part of my comment: What does the fact that we'd have to stop other work have to do with anything? That'd be the case for any workflow structure.
