typesetting.mom uses N and P for variety (demonstrating families),
but where either is used, T is an acceptable substitute.  There's no
reason to use H as the replacement.  With trivial tweaks, both the
original and the Times Roman versions produce identical layouts.

typesetting.mom currently has this:

  .ie '\*[.T]'ps' \
  .FAM      N     \" New Century Schoolbook family
  .el .if '\*[.T]'pdf' \
  .FAM      U-N

Is replacing the whole block (and the corresponding block for P) with

  .ie F NR .FAM N
  .el .FAM T

sufficient, or do '\*[.T]'ps' and '\*[.T]'pdf' still need to be
handled separately?
