Sort of, yes.

Aah. Look up the `size' feature on this page:
http://www.microsoft.com/typography/otspec/features_pt.htm
I wasn't aware that such a feature exists. The necessary information
could be rather easily added using FontForge, I think. Your request
definitely deserves a new issue in our tracker. :-)

Yes. Unfortunately, it seems that Pango doesn't support this
currently out of the box (I've just asked on the gtk-i18n-list to be
sure) which means that lilypond doesn't directly benefit.
