Hmm... As I said, I don't know much about context. But consider that 
Math-Letters is an "operator" font. If you choose futmi as your opérator 
font, something like \cos will be italicised !

Now (one of) the difference between fourier and computer modern is that 
capital greek is in the "italic" font not in the operators font.

This is handled in math-fou.tex:

\definemathsymbol [Gamma]   [alpha] [mi] ["00]
....


Note that futmi, and futmii (or futmib futmiib) are two versions of the 
same font (same encoding): the difference is that in futmmii all is 
slanted (even greek caps), and in futmii caps are upright (roman and 
greek) and lowercase are slanted.

If you want command definitions in math-fou.tex to be used even in 
boldmath, you must change type-spe.tex by referencing the fou math 
collection in boldmath too.
