Every trinitarian I have met wholly rejects the sacrifice of Jesus without really fulling realizing it until I have pointed it out. Some have seemed to smile and nod once they were made aware of it. I hope you aren't one of them.
So you can't have it both ways. Jesus can't be inseparable union of 100% man and 100% God and still die. This is precisely why there is no record of Jesus doing anything in the period between his death and resurrection, because he was dead. His body, soul, and spirit were sacrificed because he isn't God.
1 Peter 3
18For Christ also suffered for sins once for all, the righteous for the unrighteous, to bring you to God. He was put to death in the body
but made alive in the Spirit
Isaiah 53
10Yet it was the LORD’s will to crush Him
and to cause Him to suffer;
and when
His soul is made a guilt offering,
He will see His offspring, He will prolong His days,
and the good pleasure of the LORD will prosper in His hand.
