Be careful with the non-standard row stagger. That **** is just as hard to learn as any non-standard (matrix, symmetric stagger, column stagger, sculpted with height differences between columns, or whatever) board, except with fewer advantages. Switching back and forth between your proposed keyboard here and a standard keyboard is going to cause lots of annoying mistakes I suspect.
I have a couple of keyboards with non-standard stagger (1/4u each between rows) but an otherwise standard layout, and I find it really frustrating to type on them. (But I’ve never tried for any extended amount of time, so maybe you can easily get used to switching back and forth. YMMV.)
