I think gnuplot does some proprocessing on reading the data (especially if
you use "set log", or smoothing (?)), so the data may not be always
reproducible.

You can get this functionality outside of gnuplot. Just after each plot from
your front-end, do "save 'plot1.gp'" -- and there you have access to all
properties of this plot, including the "plot" command listing the datafiles.
You just have to parse the file -- I think that's how Octave's "gshow"
currently works.

Maybe using mkfifo you don't need to touch the filesystem and keep all these
options as a string list in memory of your front-end.
