Paul was adamant about each person being resurrected. Though he didn’t know the specifics of what we would become, He called it a “spiritual body”
The word “body” in Greek is “sarx” and is often used to refer to a corpse.
As someone has already mentioned, our resurrected body will be as the resurrected body of our Lord Jesus.
Some use passages like “flesh and blood cannot inherit the kingdom” to rule out a physical body of any kind.
I think that’s not right. But, we must acknowledge, as Paul did, we will not know the details this side of heaven.
So, to answer your question directly, I don’t believe someone will miss heaven if they believe a physical body cannot go there.
Peace to you
