I do not know of a convenient way to create such graphs in gnuplot.
You could plot the points themselves using parametric functions:
plot 'data' using (f($1,$2,$3)):(g($1,$2,$3))

But creating and labelling the axes would be difficult.

Sure.
You could also use SourceForge tracker site to create a Feature Request.
It sounds like an interesting project to implement this, but non-trivial.
