At the risk of sounding a bit corny,
I think this is a good step towards having a professional product.
I can't claim to know all the ins and outs of NFSS and I haven't
read the entire code he presented, but regarding the failure
of the tentative code with \halign, using \relax before the
\if statement would cure most problems of this type.
I spotted at least one potential source of problem
in the definition of \check@mathfonts.

Changing this to:

\def\check@mathfonts{%
\relax
\ifx \glb@currsize \f@size

etc. would eliminate at least one trouble spot.
