Yes, of course, this is possible. However, there is a question of priorities
and manpower. For the moment, manpower is rather limited.
You might start by describing what you did, how/why you decided to change what
you did, and what the results of each change were. Already, this would be a
big help to others.
Bacula does have some of the capabilities that you described. Some are
controlled by directives, and others are controlled by recompiling with
#defines changed in src/version.h. However, the defines are a bit out of
date and may not work. To make it all work and to put it together in a
coherent way that users can try it, is a rather big project.
