I would like to restate what you wrote here:
The hypostasis is the foundation of the ousia...
The prosopon possesses the hypostasis...
So the prosopon is in possession of the foundation of the ousia...
The ousia has a physis...
Put into English, it sure sounds like the face is in possession of the person thereby determining the being that has a nature...
That is too crackers for you to believe...
Would you please put what you wrote into some better English that my 9 year old can understand?

You don't seem to recognize or comprehend that the hypostasis and prosopon comprise the person. There is no phaino without an appearance, so there MUST be a face or presence for the hypostasis to even be created phenomena. No prosopon... No phaino. A hypostasis MUST have its own proper prosopon.
The reason the prosopon "has" the hypostasis is because it locates the hypostasis in tangible existence; just as the prosopon of Christ locates us IN Him as we're hypostatically united and seated in heavenly places.
The body was formed first, then the breath of life breathed into the nostrils; and man became a living soul.
The foundational underlying reality is the hypostasis. But until spirit-body (ousia-soma) joining, man isn't a soul (hypostasis). The body without the spirit is dead. The Spirit giving breath (spirit) to the body IS soul life (nephesh and psyche).
There are no disembodied hypostases with physical life. We are either in our own prosopon or hypostatically translated into the prosopon of Christ by faith to be IN Him. His prosopon is our robe of righteousness until the final judgment, wherein we will be clothed upon with immortality and incorruptibility with our resurrected and glorified body.
This is putting on Christ and putting off the old man with sin in its members. His prosopon "having" our hypostasis is our elpis underlied by the substance of our pistis. This is our confidence and assurance of/for our blessed hope.
Grace is the influence of God's divine nature upon our own as we're partaking of that nature IN Christ. Our human nature accessing God's divine nature through the divine and human natures in Christ, into whom we are translated. We have access by faith into the grace wherein we stand.
It's not about whether one is saved and lost or once-saved-always-saved; it's about BEING saved by BEING in Christ. Being as a copula, not a verb. A state of being, outwardly demonstrated by works of faith according to a repentant heart and mind with a changed condition.
A "person" is NOT a hypostasis, but is a hypostasis and prosopon. There are no created breath-animated living hypostases without a prosopon. The prosopon is what shines and appears, which is phaino. For a "person" to be phenomenon and exist, the hypostasis must present its appearance/face/presence AS phaino.
No need for the historical false binary of whether the "person" is the hypostasis or the prosopon. The "person" requires BOTH; the inner and the outer man. And we work out our salvation (with fear and trembling) from the inner man (hypostasis) to the outer man (prosopon), demonstrating works of faith in true piety and asceticism with unfeigned love.
Grace changing the nature of our being as we live and walk in Spirit by the faith of the Son of God.
Yes, the prosopon "has" the hypostasis, because they both comprise the "person". And us putting on the prosopon of Christ is why we are in hypostatic union with Him. His prosopon "has" our hypostasis just as it "has" His own. We are betrothed, and one in all but flesh. Then our flesh will be cleansed at the judgment for us to be clothed upon with our wedding garment to be one flesh with our Bridegroom for all everlasting.
