That could be an idea, but I've never used it in practice.  Virtual 
inheritance has always been solely an academic thing.  That's probably 
going to get pretty complicated, and one I'd think would have to 
seriously question a design that invovled virtual inheritance.  I might 
try it out just out of curiousity to see if I can get it to work.  Maybe 
if it works it might be useful if I really want to do it.  I've also 
always have wondered how virtual inheritance works under the hood, it 
might be a good time to look at that.
