I don't know the 42Plus well enough to see all the implications.
You can get an idea how it might work, by running Plus42 with the DM42 skin. You'll have to use the CATALOG to access DIRS, DIR.FCN, UNITS, UNIT.FCN, EQN, and EQN.FCN; and for R↑, X<>, VIEW, %CH, you'll have to use XEQ or the FCN CATALOG. SST↑ is in CATALOG→PRGM; for PLOT, and TVM, you currently have to use XEQ "PLOT.M" and XEQ "TVM", respectively, since I haven't decided yet how to deal with them in this scenario.
DIRS and UNITS are moved to the first row of CATALOG when a non-Plus42-aware skin is used, so it won't take too many extra keystrokes to reach them, and EQN can be reached using the white [=] key in the SOLVER and ∫f(x) menus. For me personally, that covers the most common use cases, and I could live with this arrangement, or even with a 37-key keyboard, but personal preferences will vary, of course.
I don't think the keys that are relabeled when the equation editor is active would be an issue. The symbols ( ) [ ] : = could simply be printed next to them. I went with key relabeling in the app because I could, but I don't see that as a very important feature.
