The problem is that the ones I mentioned are already defined, and I want
to remain upward compatible.

If the encoding is right, it should work, otherwise something should be
cooked up, but I fear it only works ok for a normal encoded font.

If you use it as caligraphic, then I would say: 

\definefontsynonym[RalfSmithFormalScript] [rsfs10]      % goes into
font-fil.tex

\definefontsynonym[Caligraphic][RalfSmithFormalScript]  % goes into a
style/preamble

So, no separate font file is needed, just a setting in the preamble of
your document (or your local cont-sys.tex file). I've added the rsfs
entry to font-fil.
