Is it having no effect at all, or are you getting an error message about
\UnicodeMathSymbol being undefined?
If it’s the latter, try:
\makeatletter
\let\UnicodeMathSymbol\um at mathsymbol@noparse
\UnicodeMathSymbol{"0007C}{\vert}{\mathrel}{vertical bar}
…
\makeatother
(Or maybe the \let\UnicodeMathSymbol\… is not needed? Must test.)
When unicode-math.sty calls in unicode-math.tex and
unicode-math-add.tex, the \input command is wrapped in a \makeatletter
\makeatother, and \UnicodeMathSymbol has been defined as above.

Or, taking the lead from some other packages I’ve seen, unicode-math
could look for a local file unicode-math.cfg that holds commands like
\UnicodeMathSymbol{"0007C}{\vert}{\mathrel}{vertical bar} &c.
(Can somebody get Will his magnetically-suspended table, so that he’ll
have time to work on Important Stuff like unicode-math, so that I can
work on my rocket lander? ☺
(Seriously, though, I want to thank Will for all the time he’s taken
from his thesis work to help make things work. Being in middle of a
thesis myself, I know how irritating such myriad little distractions can
be. Beer’s on me if we ever meet up.)
