Hmmm, probably missing something here, but have you looked at PathHierarchyTokenizerFactory?
In essence, it indexes each sub-path as a token, which makes lots of faceting tasks easier. I.e. lev1/lev2/lev3 gets tokenized as three tokens lev1/lev2/lev3 lev1/lev2 lev1 If that works, I'm not quite sure why you need dynamic fields here, but then I only skimmed.
