Sorry I didn't mean to suggest that such a virtual font method already
exist in xetex (at least not for large fonts as you are trying to use).
I only meant that is what you are looking for. Currently I would say
your best bet is \XeTeXcharclass. It is certainly a bit of a problem
that you can't set \XeTeXinterchartoks between a specific class and
"all others". But on the other side a normal document doesn't use 100
of classes so the work could probably be done in reasonable time with
