First, at least last time I created a compiler much less studied compilers it is not "simple" to replace keywords.
You certainly must know the semantics of the abstract token. And you must know the concrete language you want to use. This is not a job for Google Translate. But we are not talking about defining a new programming language; just modifying the symbol table used by the tokenizer. That is magnitudes simpler than making an all new compiler.

Second the latter part of that statement seems to suggest exactly the problem that compilers need to solve with the first part of what I said. Compilers (and interpreters) already convert key words into tokens. Those that do not are very inefficient (as I know since I had to work with one long ago.)
Quite to the contrary. If you store the source code by their abstract tokens, the result of the tokenizers job (and maybe even after a fundamental structure parsing), that heavy job you are referring to is done "once and for all". Or at least until the code is edited, but then a reparsing is required only for that substructure affected by the edit. Further compilation would be significantly faster, as much of the work is already done.

We have had precompiled header files for many years. This is along the same lines, except that the pre-parsed code is the primary source representation, with a mapping back to ASCII symbols is only done for editing purposes, and only for that part of the code displayed to the programmer at the moment.

Requirements, Architecture, Design are all in that natural language. All of those have much more impact on the solution than the actual code itself.
In "a" natural language, yes. English. Far too often, the design language is English, even if the customer and end users have a different natural language.

The norm is that in the very first input steps from the customer, the native language is used. Then the developers retract to their ivory tower to create The Solution, as they see it. First: Then it is back to English, and second: The ties to whatever was discussed with the customer is next to non-existing. The software structure is not a more detailed break-up of the boxes you showed the customer. The modules, functions, methods, data structure names are unrelated to the terms used in the discussion with the customer. If the customer has a complaint, saying for example "We think that when handling this and that form, in this and that procedure, you are not calculating the field with the way it should be done. Can you show us how you do it?", first: Going from the functional module and the procedure in question, as identified in the discussion with the customer, to the right software module and method in the code, may be far from straightforward. Developers do it their own way; the customer presentation is only for the customer. Second: If the developers are willing to let the customer see the code (most likely they refuse!), there is a very significant risk that the customer will have a hard time recognizing his problem: The programmers do not know the professional terminology, so they mislabel terms. They have never recognized the natural breakdown of partial tasks, solving the problem in what to the customer appears as convolved ways. The programmers have never seen the real application environment, do not know how different attributes really belong together.

If the developers did not switch from a native language to English as soon as the customer is kicked out the door, far more real domain knowledge could be preserved in the solution. In the development process, the customer could provide a lot more domain knowledge, correcting and aiding the developers as they progress with the more detailed design, and onto the code design. A customer who knows the logic of the solution, even if he doesn't know the specific code statements, is able to provide a lot more helpful feedback, both in bug finding and in discussions about future extensions and additions.

I know very well that customers without a clue about computers can give very valuable input. They can discuss solution logic. They can discuss data flows and functional groups. I have done that in several projects, serving as a messenger between the end users and the development group. (And in one library project, when I put forward the wishes from the future users, the project leader sneered back at me: "F*** those librarians! ... That was his honest attitude towards the end users; they were a source of noise, nothing more.)

My attitude towards customers and end users is at the very opposite end of the scale.
