I don't get what you're trying to prove...
The problem is that you should be comparing BT hasted renew to BT hasted [insert anything else here]. It doesn't get better than BT hasted Penance + Greater Heal or BT hasted Penance + Prayer of Healing.
I think you answered your own question there.
BT hasted Penance + Renew + Greater heal or Bt hasted Penance + Renew + (instert what ever spell) Renew doesn't consume BT so why not cast a 1 sec heal on a tank that will give 25K healing for half the mana cost of a shield. I don't really think using a spell as cheap as renew padding the meters, I think of it as smart healing. It works well for both tank healing and raid healing.
