I do not see that in the scriptures. Circumcision is a physical sign of being in a covenant with God. The sign now is the Holy Spirit and a circumcised heart.
Of course Abraham and Isaac, but not Zipporah and her son.
Let's try to reason together, since the scriptures aren't clear and many different teachers taught many different scenarios. 1. It is not clear if God was going to kill Moses, or his son; 2. and, the scriptures don't say which son, Gershom or Eliezer; 3.and, we don't know for sure if Zipporah cast the foreskin at Moses' feet, or her son's feet; 4. and finally, it isn't clear who she called a bloody husband, Moses or her son.
So with reasoning, my beliefs are 1. that since God was going to kill Pharaoh's son for not letting His people go so they can serve Him, it makes sense that God was going to kill Moses' firstborn son for not serving God by circumcising his son. 2. It makes sense that it was Gershom, since Gershom is Moses' first born. 3. It doesn't make sense that Zipporah cast her son's own foreskin at her son's feet, so I believe it was at Moses' feet. 4. It also doesn't make sense that Zipporah called her son a husband of any kind.
I believe since Moses was the one who was supposed to obey God and have his son circumcised, Zipporah does it instead, but proclaims that Moses is her bloody husband, since a husband and wife are as one flesh, and this clears Moses of any disobedience of not having his son circumcised.

Casting at feet represents the gospel . When we receive our new incorruptible bodies we can cast our crowns at his feet .
Circumcision is a physical sign of God's first born the Son of man, Jesus reckoned as Israel . The firstborn as sons and daughters called son of God in reference to the new creation. All die not receiving the new bodies which will be nether male nor female Jew nor gentile .
Exodus 4:22 And thou shalt say unto Pharaoh, Thus saith the Lord, Israel is my son, even my firstborn
.Moses who represented our unseen father is not listed in the seed of Christ (geanalolgy) as a priest .Aaron was ..Moses was as if he was our invisible God representing our Father in heaven . Usually the second born of man represents the born again seed. Abel, Seth. Isaac, Jacob ,Aaron , Eliezer. etc
“Moses took his wife and his sons, put them on a donkey, and went back to the land of Egypt.” (Exodus 4:20.)
Notice that the text says “sons,” not “son.” So Gershom had a younger brother. and we don’t know when he was born; It would seem we don’t even know his name at this point .
All of that and not a single additional word about Gershom or his nameless brother. until Exodus 18:3, 14 chapters after we first learn about the existence of Moses’ second son, we learn his name: “... and the name of the other (son), Eliezer; for he (Moses said,) ‘The God of my father is my help...’.” (Eli,...my God; ezer, ....help.)
Again the seed represent the Son of man, Jesus our brother inthe Lord .The seed was was not passed on after Moses .He did not represent the priesthood as did Aaron and then Eliezer.
Bloody husband represent the cross demonstration. The second demonstration of three different kinds following the Garden of Gethsemane, moving to the hill and the bloody cross. and finally the demonstration of the tomb.
The three days and nights demonstration done in three parts .One bloody the other two demonstrations not .
