Well, I don't know. The success of Betza notation lies in its simplicity. The meaning of most modifiers is obvious (f, b, l, r as directions m, c as move/capture), and for those who are slightly familiar with unorthodox pieces, most atoms as well (standard symbols for orthodox chess pieces, plus W, F, A and D). Perhaps they have to learn a handful of other symbols (v and s, but outside Shogi pieces tend to be fully symmetric, and directional modifiers are only very rarely needed in the first place, p and g.)
Having to know the meaning of '31 new symbols' pretty much destroys that. There is very little benefit in introducing symbols that hardly anyone would know the meaning of.
