Attached is a scheme example how to do this (it checks the duration-log, i.e.
a quarter rest has a 2-log of 2, an eighth rest has a 2-log of 3, since
1/8=2^(-3)). Quarter and eighth rests are printed the way you want them, all
other rests are printed as usual.
The example assigns that function globally. If you want it only for some
parts, you can simply remove the \layout block and do:
\relative {
e4. r8 e4 r4
\override Rest #'stencil = #ly:rest-interface::dot-rests
e4. r8 e4 r4
\reset Rest #'stencil
e4. r8 e4 r4
}
Also note that I changed the circle call from a radius of 0.6 and a thickness
of 0 to a radius of 0.55 and a thickness of 0.1 (half of the thickness will be
outside the radius, half of it inside!), because then you get nice anti-
aliasing and the circle will look really rounded.
I've also added that snippet to the LSR, together with some explanations:

% Our own stencil for rests: quarter rests are shown as a centered filled circle,
% eighth rests are an underlined filled circle:

(circle (ly:stencil-translate-axis (make-circle-stencil 0.55 0.1 #t) 0.3 X)))

% If you want this rest style only for some parts of a score, remove the
% \layout block above and simply override the Rest stencil wherever you want.
% After the block with circle rests, simply revert the stencil property to its

% \relative {
% e4. r8 e4 r4
% \override Rest #'stencil = #ly:rest-interface::dot-rests
% e4. r8 e4 r4
