Not sure what you mean. Perhaps FullGraphics is what you need?

In[43]:=
?FullGraphics

"FullGraphics[g] takes a graphics object, and generates a new one in
which \ objects specified by graphics options are given as explicit
lists of graphics \ primitives."

PlotStyle you'll have to program yourself, by pairing the styles with
each Line. PlotRange is an option to Graphics too. There are few
options in ParametricPlot but not in Graphics... but I'm not sure what
you want to do.
