You didn't ask, but I will note here that you only need to supply the Reg B appraisal copy notice once, since that satisfies the notice requirement in Reg. Z 1026.35(c)(5).
Next, and perhaps obvious, the one appraisal developed for the application would have to satisfy the more demanding requirements for the HPML appraisal.
As to sending two copies of the same appraisal, I believe that sending one copy satisfies both requirements. Just be certain to document that you sent it.
As to the waiver question, you would not be able to accept any waiver, since there is no waiver permitted under the HPML appraisal rule.
