A quick testing shows that this can indeed be a big problem. Say,
U+1D400 U+0301 looks very bad if both characters are from Cambria Math;
rather bad when they are from Code2001. At least MS Word 2007 seems to
be unable to tune the rendering of the combining mark according to a
base character from the SMP.

But this might depend on the rendering software _or_ on the font—there
are few fonts that contain SMP characters, and the information they have
might be insufficient fur purposes like placing a diacritic mark.
