I think you're fundamentally misunderstanding the problem.
We do have a problem with nomenclature being fractured, even within fields, never mind between them. But that's not the problem.
The problem is that when you get deep enough into how things work, things just get really complex and they stop behaving in ways and patterns that humans experience the world. They end up being things that cannot be simplified down to a common human experience in any meaningful way. At best, you can take a portion of the concept and make an analogy to some limited portion of a common experience without lying too much. But they are fundamentally not the same, so you cannot use the analogy to discover anything new about the original concept.
There is also a problem of the time it takes to internalize new ideas and concepts. You can't quickly and easily give someone an intuitive understanding of anything - it takes work and experience and time on their part to get there. I don't see how going and reworking nomenclatures of entire fields is going to make people more willing or able to devote their time to this. Mostly you'll have to put in incredible amount of work, convince far too many people to do things a different way because you said so, and all you'll have really done is save some (significant) annoyance from students getting their feet wet in a new field.
