I am resending this in the hope that some font will find him/herself with
time to consider an odd query.

I need to substitute the regular and italic characters of a publisher’s
non-math font (Unicode) for those in a math font.

The non-math addresses are:
0041-005A, 0061-007A %italic uppercase and lowercase
0391-03A9, 03B1-03C9  %slanted Greek uppercase and lowercase

The math addresses are:
1D434-1D44D, 1D44E-1D467 %italic uppercase and lowercase
1D6E2-1D6FA, 1D6FC-1D714  %slanted Greek uppercase and lowercase

Is there a way to use the \definefallbackfamily mechanism that does not
assume that the characters have the same Unicode addresses? Or is some
other approach required?
