I think your observation that globulars are sort of mini gallaxies has some truth in so far as there is support for the proposition that they are the remains of different small gallaxies that has had their outer stars stripped when meeting the larger gallaxy.
I can not give you a link to support the proposition but it sounds reasonable given the way they present, the ages of the stars within and their orbits around the "big" gallaxy.
Which raises the question "Is there a globular associated with the recently discovered remnants of the dwarf gallaxy found in Sagitarius"? I had not thought about it until now but if the above has any merit one would expect to find one I guess. Now there is a search project for all to engage in.
