that is relatively easy: just make a lfg file that contains the 
specification (and choose some math font that suits)

my guess is that it will look bad in most cases

we might consider making a sort of generic partial math font (maybe even 
needs to be designed) that sort of fills in the usual bits and pieces 
(root signs, arrows etc) in a way that matches an average font

(we probably need a few weights then)

of course that would only work for not too fancy math
