I'm not sure how what you propose works with the doctrine of the trinity, but that is for others to muddle through as I reject that particular doctrine.
I agree that what happened on the cross wasn't about punishment and wrath. As the bible speaks of the cross it lends credence to what you are proposing:
Hebrews 2:10 In bringing many sons and daughters to glory, it was fitting that God, for whom and through whom everything exists, should make the pioneer of their salvation perfect through what he suffered.
Hebrews 5:8 Son though he was, he learned obedience from what he suffered 9 and, once made perfect, he became the source of eternal salvation for all who obey him
God loves the world and sent his son and the cross had some measure of impact on him. I don't think the cross was 100% Christus Victor, but it was a big part of what happened on the cross.
Your point number 6 is interesting:
6) In PSA, you wonder what role the resurrection of Christ plays in man’s salvation, for man is saved when Christ dies as a substitute by taking the punishment of God upon Himself. In PSA, it is the “sin guilt” or “sin debt” that is the primary problem, and Jesus Christ, in a legal sense, accepts that “sin guilt” and its punishment upon Himself. In Christus Victor, man is still in His sins(1Cor 15:17) if Jesus Christ is not raised from the dead. That is to say, man is still in the pit of sin and death and sin and death is still lording over him if Jesus Christ is not raised from the dead. In Christus Victor, a dead savior cannot save. Man needs a risen, exalted, enthroned, glorified, empowered, living Savior Who is the source of life (the bread of life, the water of life, the resurrection and the life), spirit, resurrection, righteousness, and strength and Who can give these things to whom He will.
Maybe I would say it differently:
- If the death of Jesus pays the sin death and takes our punishment (i.e. PSA), then even if Christ died and stayed dead, the saints are still raised. This contradicts 1 Cor 15:15.
- We are not saved by Christ's death, we are saved by his life (Rom 5:10).
The point of the crucifixion of Christ was not to placate the wrath of an angry God who needed to be appeased by the blood of Crist. The point of the crucifixion of Christ was so that the blood of Christ could clean our consciences (Hebrews 9).
