Or \set at fontsize could be overloaded for this, e.g.:

\makeatletter
\let\org at set@fontsize\set at fontsize
\def\set at fontsize#1#2#3{%
  \@defaultunits\@tempskipa#3pt\relax\@nnil
  % \advance\@tempskipa by 0pt\@plus 1pt\relax
  \advance\@tempskipa by 0pt\@plus .2\@tempskipa\relax
  \expandafter\set at fontsize@i\the\@tempskipa\@nil{#1}{#2}%
}
\def\set at fontsize@i#1\@nil#2#3{%
  \org at set@fontsize{#2}{#3}{#1}%
}
\makeatother
