That would be a great improvement for the 'sets' feature in poudriere.
Almost all of my different sets have some overlap. Although this would
either require the 'queue' system you are working on, to say build sets
X, Y, and Z, and if there is any overlap share it. Or, augment the set
feature with an additional flag to specify a 'parent' set or something,
-z myset -Z commonset to tell it an already built set where it can steal
packages from.
