For that use I'd think
a variant declaration which would define \mathbf to flip the mathcodes into the U+1Dxxx block

So long as one minds the gaps in U+1Dxxx (actually the several gaps for which the unicode folk seem to have thought the characters were previously defined in the U+21xx block), though maybe it's not that much of an issue for \mathbf itself as opposed to \mathcal, \mathfrak, and \mathbb.

At least they were thoughtful enough to leave those slots empty.  :-)

Just seizing the opportunity to make everyone aware of the gaps.
