I found the code to reset a LaTeX font definition.
If you put \maybe at onum in your .fd file and load the font like usual, you can then execute this:

      \csname\f at encoding/% 
             \f at family/% 
             \f at series/% 
             \f at shape/% 
             \f at size\endcsname 

to forget about the font, then change \maybe at onum, and reload the font.

But please don't use the same macro names as fontspec, as I'm sure it will only lead to confusion :)
