That's not a license to indulge your own ideas. We need to find what "He" meant, not come up with new ideas and use this symbolism and metaphors after the fact as support.
There are anchors for metaphors and symbolism in the New Testament.
Revelation 12:1 And there appeared a great wonder in heaven; a woman clothed with the sun, and the moon under her feet, and upon her head a crown of twelve stars:
Genesis 37:9-10 And he dreamed yet another dream, and told it his brethren, and said, Behold, I have dreamed a dream more; and, behold, the sun and the moon and the eleven stars made obeisance to me. [10] And he told it to his father, and to his brethren: and his father rebuked him, and said unto him, What is this dream that thou hast dreamed? Shall I and thy mother and thy brethren indeed come to bow down ourselves to thee to the earth?

Matthew 13:36-37 Then Jesus sent the multitude away, and went into the house: and his disciples came unto him, saying, Declare unto us the parable of the tares of the field. [37] He answered and said unto them, He that soweth the good seed is the Son of man;...

Luke 22:19 And he took bread, and gave thanks, and brake it , and gave unto them, saying, This is my body which is given for you: this do in remembrance of me.
Obviously it wasn't his flesh, because his flesh was still standing there holding the bread and he didn't rip off his flesh and hand it to them. The remembrance precedence he was setting here was just unavoidable, especially since He said it was for remembrance.

John 2:19, 21-22 Jesus answered and said unto them, Destroy this temple, and in three days I will raise it up. [21] But he spake of the temple of his body. [22] When therefore he was risen from the dead, his disciples remembered that he had said this unto them; and they believed the scripture, and the word which Jesus had said.
The men the Bible documented had their own meaning behind their symbolisms. They all have anchors, Not permitting for us to go off with new meanings according to our own mindsets. NOONE in the Bible ever connected Jesus's three days raising His temple with the timing of His return. There is no Biblical anchor for this.
That Jesus used a metaphor, "Tear down this temple and in three days I will raise it up again", about his own death and resurrection, is indeed an undeniable fact.
That there will be a resurrection of the dead is another undeniable fact.
That Jesus connected His own resurrection to the timing of His return to resurrect His followers is nonexistent and a pure fabrication.
The two undeniable facts stand ALONE and do not support the pure fabrication.
