Here's the gotcha. For a full ILS approach, you also need an inner marker. There is no substitute for an IM, and the books are silent about the affect of no IM. Without it, I must conclude that the ILS approach isn't legal and it reverts to non-precision LOC. Again, I don't think anybody really gives a Rhett Butler; track the GS until Decision Height. That's my reading of the FARs and AIM, because I considered the same question as you for the first RV.
