I had a similar idea, but never got to think about it in details.
Another thing currently missing (at least in Pango) is proper
fallback when fonts don't have certain features (say kern, mark,
mkmk, ...) We currently have a fallback implementation that is
only used (sometimes never used, depending on the backend) if the
font has no OpenType features. I think we need a more
fine-grained fallback mechanism.

The license is indeed a problem. The current license of HarfBuzz
makes it usable in both Pango and Qt, but limits possibility of
moving code from Pango's shaper modules to HarfBuzz for example.

That's the hard part. Unless you specifically have somebody in
mind that can do this, I don't think we will get any qualified

That's not the hard part. I'm willing to mentor such a project,
and I think we can get Lars to help too. GNOME will be happy to
host it. Feel free to add the idea here:
