--------------------------------------------
You can combine more fonts, if you register them to another
math families (5, 6, 7, etc.) in \normalmath macro.
The default value of \normalmath shows a combination of base Unicode Math
font with 8bit Math font at family 4. See definition of \script macro where
\fam4 is used. Of course, we need to set \rmvariables too, because 8bit font
accepts only codes less than 255.
See http://tex.stackexchange.com/questions/308749/ for more technical details.
The poor bold is used for complete bold vaiant of the font. If the selected
font has its bold vaiant (like xits-math), you can re-define \boldmath macro
by:
\def\boldmath{%
\loadumathfamily 1 {[xits-mathbold]}{} % Base font
\loadmathfamily 4 rsfs % script
\setmathdimens
}
