The real point of the post was to explore if a set of alternate functions (like TVM in place of default SQRT, X^2, etc.) could be re-mapped to the keyboard via some user-selectable setting. Such a framework would allow future variations to more easily implement new "built-in" functionality, only requiring different overlays. It also would allow these variations, or contributions to them, to come from additional developers who may not need to learn all the 31S/34S internals in order to contribute some new feature. Just wondering out loud.

Is this feasible, without lots of redesign, etc?

I'd guess not. Sometimes in life, decisions are simply inevitable.

• If you want an "eierlegende Wollmilchsau" (jack of all trades device) then get the WP 34S where Franz' TVM program is included in the library.
• If you prefer a very clean surface of a scientific calc instead, get the WP 31S.
• If you want a business calc, stay with the HP-30b.
• If you want something different than the ones mentioned above then design a 32S (remember the HP-22).
• If you want a chameleon, invent.

Looking forward to your results.
