Clearly you're asking for a standard way. I can't provide that--only Hans
can--but I can suggest a solution that I have been and still am working
on. I'm defining some new fontstyles for each of sans and serif, CapsSans
(cs) and RomanCaps (rc). The basic definitions look something like:

\starttypescript [serif] [romancaps] [size]
 \definebodyfont
  [17.3pt,16pt,14.4pt,13pt,12pt,11pt,10pt,9pt,8pt,7pt,6pt,5pt,4pt][rc]
  [tf=SerifCaps sa 1,
  tfa=SerifCaps sa \magfactor1,
  tfb=SerifCaps sa \magfactor2,
  tfc=SerifCaps sa \magfactor3,
  tfd=SerifCaps sa \magfactor4,
   bf=SerifCapsBold sa 1,
  bfa=SerifCapsBold sa \magfactor1,
  bfb=SerifCapsBold sa \magfactor2,
  bfc=SerifCapsBold sa \magfactor3,
  bfd=SerifCapsBold sa \magfactor4,
   it=SerifCapsItalic sa 1,
  ita=SerifCapsItalic sa \magfactor1,
  itb=SerifCapsItalic sa \magfactor2,
  itc=SerifCapsItalic sa \magfactor3,
  itd=SerifCapsItalic sa \magfactor4,
   bi=SerifCapsBoldItalic sa 1,
  bia=SerifCapsBoldItalic sa \magfactor1,
  bib=SerifCapsBoldItalic sa \magfactor2,
  bic=SerifCapsBoldItalic sa \magfactor3,
  bid=SerifCapsBoldItalic sa \magfactor4]
\stoptypescript

\starttypescript [sans] [sanscaps] [size]
\definebodyfont
  [17.3pt,16pt,14.4pt,13pt,12pt,11pt,10pt,9pt,8pt,7pt,6pt,5pt,4pt][cs]
  [tf=SansCaps sa 1,
  tfa=SansCaps sa \magfactor1,
%%  ...
  bid=SansCapsBoldItalic sa \magfactor4]
\stoptypescript


If you create font synonyms for each of the three extra symbolic names
for each font, and use the above typescripts, then you can call the Small
Caps font directly with a style switch (\rc\bi), with a style switch, but
keeping the alternative (\switchstyleonly\cs), or with the following
\SmCap macro, which tries to be a little cleverer about the available
alternatives. I haven't worked the ungrouped \kap command into it,
because I'm not sure how.

\def\SSSmCap{ss}         \def\SSmCap{cs} % Don't know how else to compare.
\def\SmCap
 {\ifx\fontstyle\SSSmCap\doifdefinedelse{cs}
      {\switchstyleonly[cs]}{\sc}\else
  \ifx\fontstyle\SSmCap        \else%   Do nothing: we're already there
                        \doifdefinedelse{rc}
      {\switchstyleonly[rc]}{\sc}\fi\fi}
\let\OldStyle\SmCap


[be gentle... it's my first command with lower-level macros]

I'm hoping to write this up as a "My Way" before too long, but I wanted
to get this idea out there for some feedback. As my recent posts suggest,
it requires some extra font memory.

hope that's of some use,
adam
