Feasible certainly: assuming the X11-version of PfaEdit has been 
installed (this is done automatically by the corresponding i-Package if 
X11 is detected on your machine), launch X11, from it run PfaEdit 
(/usr/local/bin/pfaedit), open the four fonts in 
/usr/local/teTeX/share/texmf.gwtex/fonts/type1/adobe/utopia (you can 
select all four of them together inside PfaEdit's Open dialog), bring 
the Utopia-Regular window upfront, select "Generate Mac family…" in the 
File menu and proceed. A .dfont file is generated (you must select a 
directory outside the original one, with is not writable).

As to whether this is legal, I don't know. I think William Adams said 
once that Adobe's license allows conversion, I'm not sure. The Utopia 
license is included in /usr/local/teTeX/share/texmf.gwtex/README.utopia 
and doesn't say anything about conversion:

The Utopia fonts themselves are governed by the following liscense.

This is a copy of the Utopia Type-1 fonts which Adobe contributed to the
X consortium, renamed for use with TeX:

   Utopia-Regular
   Utopia-Italic
   Utopia-Bold
   Utopia-BoldItalic

Maybe you must make sure the above copyright is included in the .dfont 
file as a comment, if such comment actually exists in a .dfont file.

The above won't give you math characters, which is what Fourier fonts 
were developed for in the first place, i.e. a math complement for 
Utopia. Surely PfaEdit will produce Mac fonts out of them, but the 
problem will then be: where to put the math characters, so that you can 
see them.

In a thread a couple of weeks ago, people mentioned that the Symbol 
font has been reimplemented by Apple specially for OS X, so that the 
mathematical characters it contains are now positioned at their 
appropriate Unicode slots, not at the usual 256 slots of a PostScript 
font (this is not fully correct, a PostScript font can have more than 
256 characters, only a PostScript encoding vector is limited to 256 
characters, but that's the idea). The bad side of this is that now you 
can't use the keyboard to directly input the math characters from 
Symbol in a document, even in this font the keyboard will only give you 
"normal" characters (those printed on the keys), you have to use the 
Character Palette instead, or switch to Hex Unicode Input (both the 
Character Palette and Hex Unicode Input are activated in System 
Prefs/International/Input Menu).

Maybe the huge work that Gerben has done (in collaboration with George 
Williams, the creator of PfaEdit) for converting Latin Modern fonts to 
Mac format can be adapted to Fourier fonts, I don't know.
