I'm not deeply familiar with the WGT hybrid apps, but "web UI supplemented
by C/C++ code" is basically how crosswalk's existing extensions process
works:

https://crosswalk-project.org/documentation/tizen_ivi_extensions.html

There may be details that need to be worked out to make it more compatible
with the WGT/WRT model.  I'm guessing there may be no way to start the
native portion without a UI (as extensions are intended to be like
libraries and called as such) so there may need to be some logic added if
that's required.  Support for long-running processes should be doable with
web workers right now.

If we're talking about direct backwards compatibility of all existing apps,
I think we might need a script to convert packages, and I'd be surprised if
a few issues didn't come up once we started looking at each one.  But in
spirit, at least, crosswalk already supports hybrid apps on Tizen.
