Rather than shrinking, squash the fake small caps, eg:
S\H'\n[.s]*5/7'MALL\H'0' C\H'\n[.s]*5/7'APS\H'0'
(the 5/7 should approximate to the x-height of the font).
This works better because more of the heavy strokes in a western font
are upright, and this keeps the weight of those.
As Matthew Butterick says
"If you want real small caps, you'll have to buy them"
I have such a set, but the newer version contains OpenType faces and I
haven't had time to work out how to use these with groff. The small cap
glyphs are named something like A_sc -- tricky.
I have a macro analogous to the .B, .BI macros of man pages: .SC ...,
but it works differently to Ted's ingenious solution, involving .substr.
