Not meaning to pre-empt Will's answer, but I think that this currently 
doesn't work. On the other hand, if you had a "spare" maths alphabet 
then you could do something along these lines:

\DeclareMathSymbol{0}\mathalpha{operators}{"30}
\DeclareMathSymbol{1}\mathalpha{operators}{"31}

etc...

You have to be a bit careful with scaling fonts or maths as a whole with 
this, but the approach works well enough that I'm using it in a 
maths-heavy PhD thesis against the time when unicode-math is ready for 
full scale deployment...

Hope that helps,

David
