I may be missing what you mean, because it seems to me that any set of bit strings (even of variable length) is aggregatable to an arbitrary extent. Just build a binary tree and chop it off at whatever level you want (/N if you want 2^N aggregates). (The equivalent has to be true for namespaces using n-ary instead of binary symbols.)
