Where could itadori's child (if he hypothetically had one) be projected to reach?

Say current, prime Itadori Yuji (BM, BF Affinity, His Shrine, unaging + 80 years of experience) was to hypothetically have a child - given itadori is who he is with his natural stats + vessel + affinity;

1. What CT would they have?
2. Where do you think their ceiling for potential would be?
3. Just for fun how far do they make it through the JJK verse?(not modo)?

Just curious to see what thoughts would be
