along these lines:
\def\useGNUPLOTgraphic
{\dotripleempty\douseGNUPLOTgraphic}
\def\douseGNUPLOTgraphic[#1][#2][#3]%
{\itthirdargument
\dodouseGNUPLOTgraphic[#1][#2][#3]%
\else\ifsecondargument
\def\docommand##1{\dodouseGNUPLOTgraphic[#1][##1][#3]}%
\processcommalist[#2]\docommand
\fi}
\def\dodouseGNUPLOTgraphic[#1][#2][#3]%
{\getparameters[#1:#2][#3]}
etc etc
you can also check for \doifsssignmentelse{#2}{...}{...}
