This is very close to the OEB that came out a few years ago. I believe that one was more towards blocked pitot tubes because it is now incorporated into the unreliable airspeed checklist. Essentially, you are doing the same in both procedures. In normal law the airplane's protections might get you into trouble with frozen AOA vanes (or blocked pitot tubes). So turn off two ADRs and presto you're in alternate law without those protections and should be able to fly out of the situation.

For extra points.......check out your cockpit pictorial and find the alternate PFD display for aircraft 607NK and subsequent (maybe 605 and subsequent). What's the BUSS and when would it come up?
