Here is a little problem from my work:

We have an axial coupling constant, conventionally called $g_A$. However,
in this combination the A' does not really look subscript. After some
experimenting, I came up with the following: $g_{\text{\sc A}}$ which looks
fine. That the A' is now upright is not that bad in this case, in fact it
is not a mathematical symbol but has textual semantics.

I think this little problem should have a more general solution. I imagine
a style which prescribes different sizes for subscripts, depending if a
lowercase letter is subscripted or a capital one. Since I have not tried
it, I don't know how difficult to achieve this might be.

Just to provoke ideas...
