Isn't it more or less (but with a simpler interface) the way Omega  
works already, which introduces Unicode virtual fonts grouping  
together several actual fonts so as to fill in the whole Unicode  
range? I imagine font specialists would retort this will produce less  
than ideal aesthetic results, results that are not typographically
