It is quite clear that you and Jaded are much more interested in making your own more specialized packs (To such a degree that it seems some of the official FTB packs have become quite neglected IMO). But would it not be possible to recruit/hire/whatever someone to continue the tradition of the "large builders paradise" packs?
U might be looking at something along the lines of TPPI (test pack please ignore)?. From what i recall, its a ftb-comunity made private test, and it has a pretty nice setup and maintenance.
