I don't think you would want to have this depend on using TTC packaging:
you would want it to work even if the fonts are packaged as WOFF.

It's clearly a significant limitation of OpenType at the moment that
cross-font shaping is not possible.  However, fixing this would be a very
non-trivial change to OpenType layout. If the CSS WG thinks this is a
limitation that it's important to remove, then I would suggest the W3C
should submit a reasoned request for this to the responsible ISO WG. I
believe there already is a liaison relationship in place.
