As an addendum to your reply to Diversification, I would say that in an earlier discussion it was determined that once in ALTLAW2, Normal Law is inop for the rest of the flight, until the system can be re-indexed.
My recall of the B-2 Guam crash is that in re-indexing the computers in the evening prior to launch, the ground crew neglected to dry out the sensors, and the data loaded was bunk for TO. GIGO. The pilot's of the Liberty had no mystery, when the Computers yack, Adios amigo. Not so pretty clear with AB.
Re 447, a transport of conventional airframe architecture, one could start a train of thought that included, "If not in Normal Law, then straight to direct." The B-2 cannot be flown in any fashion by hand, so its experience is suggestive only. One gets the notion in following this (AB) discussion that in the stink, one needs to know how to fly at least four different a/c.
One cannot wish to hire BoxMonitors and also expect a "Four-in-one Type Rating." Aviation will NEVER be so predictable that one can expect pilots under normal circumstances to revert to "golden arms"* on a milsec's notice.

I think it fair at this point to say "Raise the Nose Up". There is precedent, and neither can be supported by the information at hand, at least not conclusively. Finally getting the nose down, the crew may have succeeded too well, and could not raise it once again. It fits into what happened at Perpignan (loosely).
There was a Pitch problem by definition. Considering the RoD, why not at least consider more than one "recovery" of Pitch authority?
aside. BUSS was one of two systems discussed earlier, along with the unselected AH at the upper left of Captain's Panel. Bean counting can bite.
