Hm, well then, your need seems "bloated". You don't need _whole_ Central Repository GAVs at all (what for? to use 1%, 5% or 10% of it in best case?)...
Let's reverse your problem: Just create those "local POMs" first, and use Aether [1] to resolve it's dependencies and persist somehow the resulting tree. The tweak your local POM (apply changes you mention, bump some versions or add some) and persist that tree too. And then compare the two tree, visualize or whatever. So, you could figure out how to persist the dependency trees got from Aether (it calculates for you all), how to compare the trees and finally how to visualize those diffs. That would be a nice thesis :D Ultimately, the "tool" resulting from your thesis could be applied to _any_ project, just pass in the POM of it in multiple iterations (ie. V1, V2, ...), build the graphs, and resulting output would be nice visualization of "changes" happened in dependencies. Note: "getting dependencies from POM" is not trivial. It's not just parsing the POM XML etc... you need to interpolate values, apply parents, etc... All that is done by Aether for you.
