something like this, with mtxrun --script plain test.tex

%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%
%% test.tex
%%
\outputmode=1
\edef\pdfcompresslevel {\pdfvariable compresslevel}
\edef\pdfminorversion{\pdfvariable minorversion}

\let\pdfximage\saveimageresource
\let\pdfrefximage\useimageresource
\let\pdflastximage\lastsavedimageresourceindex

\pdfminorversion=7
\pdfcompresslevel=0

\topskip0pt

%% insert page 10 from luatex.pdf
\pdfximage width \hsize height \vsize page 10
{luatex.pdf}\relax\hbox{\pdfrefximage\pdflastximage}\relax\eject

\bye
