I guess you need two hooks, a pre-commit hook and a hook which runs when
a commit is aborted so that you can roll back your changes.

In almost all cases, your approach will add spurious conflicts if you
merge from several branches where this feature is used.  Maybe you can
use something else to construct the data you need?
