I was in fact just looking at the jb pack today.  (I was trying to see 
if I could speed up Soot by not building good Jimple for library 
classes.  Unfortunately, it seems that if you build worse Jimple, then 
the subsequent analyses --- at least those for abc --- take more time. 
You can actually speed up Soot itself if you don't clean up the Jimple.)

The jb pack is sort of weird in that there are a bunch of things 
happening inside; for instance it conditionally executes the local name 
splitter and runs some timers.  These could be done by manipulating what 
gets put into the pack instead; that would probably be a good idea.

The code to populate jb is in PackManager and the code to run the 
analyses is in JimpleBodyPack.  If you want to fix that, it's probably 
not a bad idea.
