I see you are post-processing to add transparency:
 set terminal povray
 set view 70,305
 set out "tmp.pov"
 # klein.dat is one of the gnuplot demo data
 splot "klein.dat" with d
 set out
 ! sed 's/Red/Red filter 0.5/' tmp.pov > povray-demo3.pov 
 ! povray +FC +A0.1 +I povray-demo3.pov

Would it make sense to extend gnuplot's color specifications
to include an alpha channel?
I'm not so sure that's a good idea, actually.
It might make sense, however, to have transparency be an 
attribute of each surface as a whole.
Something like:

  plot "foo" with pm3d transparent, "baz" with pm3d solid
