IMO Propitiation toward reconciliation was not possible before the cross.
A really good read on the topic of the timing of sins placed on Jesus is

Typology of the Resurrection of Christ
Feast of Unleavened Bread Leviticus 23:6-8 this small amount was very important because no one was to eat anything from this first harvest until the sheaf of the first-fruits had been waved before the Lord, Leviticus 23:14
Once this sheaf had been accepted by the Lord, the nation could be sustained by the new grain.
This pictured, in advance, God the Father accepting Jesus Christ who was the first one to be harvested in order to provide the means through which all sinners could be forgiven and, upon repentance, receive the gift of everlasting life
John 20:17
Jesus said to Mary Magdalene "Do not cling to me, for I have not yet ascended to my Father; but go to my brethren and say to them, I am ascending to my Father and your Father, and to my God and your God"
John 6:35
Jesus said to them, “I am the bread of life. Whoever comes to me will never be hungry, and whoever believes in me will never be thirsty.
John 6:48
I am the bread of life.
John 5:39-40
“You search the scriptures because you think that in them you have eternal life; and it is they that testify on my behalf. Yet you refuse to come to me to have life.
The wave sheaf offering
Leviticus 23:12, Exodus 12:3-5 Requirements of the Almighty; Waving of a sheaf of the first-fruits, the significance of the sheaf is its newness as the very first of the first-fruits of the harvest. The Irsaelites carefully noted the first buds and tied a red ribbon around them to make sure that was what was offered. And the perfect male lamb offering. Refering also to the Passover lamb without blemish, just as the wave offering lamb.
Leviticus 23:14
You shall eat no bread or parched grain or fresh ears until that very day, until you have brought the offering of your God: it is a statute forever throughout your generations in all your settlements.
1 Corinthians 15:20-23
But in fact Christ has been raised from the dead, the first fruits of those who have died. For since death came through a human being, the resurrection of the dead has also come through a human being; for as all die in Adam, so all will be made alive in Christ. But each in his own order: Christ the first fruits, then at his coming those who belong to Christ.
Accepting Christ as our Passover, we should also accept him as the first-fruit offering. This leads up to “The Feast of First-Fruits” otherwise known as “Pentecost”.
John 20:1
Early on the first day of the week, while it was still dark, Mary Magdalene came to the tomb and saw that the stone had been removed from the tomb.
John 20:11-17
But Mary stood weeping outside the tomb. As she wept, she bent over to look[a] into the tomb; and she saw two angels in white, sitting where the body of Jesus had been lying, one at the head and the other at the feet. They said to her, “Woman, why are you weeping?” She said to them, “They have taken away my Lord, and I do not know where they have laid him.” When she had said this, she turned around and saw Jesus standing there, but she did not know that it was Jesus. Jesus said to her, “Woman, why are you weeping? Whom are you looking for?” Supposing him to be the gardener, she said to him, “Sir, if you have carried him away, tell me where you have laid him, and I will take him away.” Jesus said to her, “Mary!” She turned and said to him in Hebrew, “Rabbouni!” (which means Teacher). Jesus said to her, “Do not hold on to me, because I have not yet ascended to the Father. But go to my brothers and say to them, ‘I am ascending to my Father and your Father, to my God and your God.’”
Here we see that the Messiah had not yet risen to the Father. He had not yet become the first-fruit of all mankind.
The symbolism of the wave offering is the ascension of Jesus Christ to our Father as first of the first-fruits.
The timing of the ascension to the Father of Jesus Christ, and the sacrifice of the unblemished first-fruits lamb occurred at the same time. Just as the timing of the Messiah giving his life for mankind occurred at the same time as the unblemished Passover lamb was sacrificed.
The single male lamb without blemish is a commanded sacrifice on only two set apart feast dates. One being the Passover lamb and the other being, the Wave Offering lamb.
1 Peter 1:18-21
You know that you were ransomed from the futile ways inherited from your ancestors, not with perishable things like silver or gold, but with the precious blood of Christ, like that of a lamb without defect or blemish. He was destined before the foundation of the world, but was revealed at the end of the ages for your sake. Through him you have come to trust in God, who raised him from the dead and gave him glory, so that your faith and hope are set on God.
