What we have been doing to solve this is that we maintain a git branch
of buildroot with our components added as buildroot packages. Our
applications appear in a dedicated submenu and are built as part of the
standard buildroot process. This is similar to what you are suggesting
and it is already very easy to achieve by means of a git branch. Doing
it this way also has the advantage that it also solves the problem of
distributing your project files to co-workers as everything is kept
under version control. Changes from buildroot upstream can easily be
merged into your branch and are then also easily distributed to
co-workers and to your build system.
