How are you planning on doing this identification? Looking at
the arch logs, it is not trivial to identify merge commits and the
upgrade patches (which are just merges from the upstream branch),
unless you start with an ancient version (like, from my 2003 repo) and
then apply every single commit to the integration branch over the last
five years (with really really huge numbers of patches).
You'll have to track repo changes, figure out how to overcome
sealed branch boundaries, etc.
I am not sure I believe this to be feasible until I see some
code.

No, it does not. If branch A has
pi = 2.34567;
and branch B has
pi = 3.14159;
No matter how much quilting you do you cannot reconcile the
fundamental conflict in the final. Either pi is 3.14159; or it is not;
and if branch A requires pi not to be that value, and branch B requires
pi to be that value, quilt can't make C be quantum like and have the
value be both.
