1. plain TeX: \advance\baselineskip 0pt plus 1pt; 
LaTeX: \addtolength{\baselineskip}{0pt plus 1pt} with \flushbottom. 

2. However, \baselineskip is reset with every \normalsize. 
bk12.clo, e.g., has 
\renewcommand\normalsize{%
 \@setfontsize\normalsize\@xiipt{14.5}%
  ...

copy the entire definition between \makeatletter ... \makeatother 
and replace {14.5} by {14.5 \@plus 1pt}

... do you see a difference?

Cheers,
