Uh uh -- no it won't ...

   ... since \mkfont is undefined upon leaving that last '}'
closing the \makeatletter grouping.


What you need is:

{\makeatletter \nfss at catcodes \globaldefs=1
  \newcommand\tmpmkfont{%  <------------  beware this space
   \DeclareFontFamily{U}{fontB}{}%
   \DeclareFontShape{U}%
     {fontB}{m}{n}{<-> s*[0.5] "Didot"}{}%
  }
  \global\let\mkfont\tmpmkfont  % <-------- keep a \global pointer
}


The extra space is probably harmless, especially if the font
definitions are read when in the LaTeX preamble --- but that's
not always the case, so best to avoid it.

The need for a \global macro name is *vital*.
Now \tmpmkfont goes away, but \mkfont remains.


Cheers,

	Ross
