It works for me:

$ pdffonts ~/courier.pdf  -subst
name                                 object ID substitute font                      substitute font file
------------------------------------ --------- ------------------------------------ ------------------------------------
Courier                                   7  0 Nimbus Mono L                        /usr/share/fonts/type1/gsfonts/n022003l.pfb
Courier-Bold                              8  0 Nimbus Mono L Bold                   /usr/share/fonts/type1/gsfonts/n022004l.pfb
Courier-Oblique                           9  0 Nimbus Mono L Regular Oblique        /usr/share/fonts/type1/gsfonts/n022023l.pfb
Courier-BoldOblique                      10  0 Nimbus Mono L Bold Oblique           /usr/share/fonts/type1/gsfonts/n022024l.pfb

With versions 0.48.0 and from git master.
