That's an interesting idea; in effect, it would be shorthand for some 
fancy macros that retrieve \fontname, parse it to extract the 
name+attributes and size, append a new attribute, and define a new 
\font. Right?

(I imagine that could simplify things internally for Will's fontspec 
package, too.)

I'll think about it and see if it seems feasible and robust.
