Hi Grzegorz,

I'm afraid this is an artificial limitation in fontspec at the moment 
-- it's been reported to me in the past but I haven't had the 
opportunity to fix the problem. Clearly, the thing that should work is:
    {Size=10.5-11.5,Font=...,ItalicFont={* Italic}}
(if necessary at all when the ItalicFont isn't picked up automatically) 
but the fact that it doesn't is plain and simply a bug.

Not much time right now, but I'll try and take a look sometime. If you 
see anything in the code that makes this a quick fix, feel free to pass 
it along :)

Sorry for the inconvenience,
Will
