... Bishops can sign agreements, but the Orthodox Faithful know that the patriarchs under the Vatican receive the pallium from there to reflect its theology, that the Vatican's priests cannot marry and know that a whole theology has been built up to justify that, that the Vatican's infants cannot be chrismated and whole theology has been built up to justify that, etc. (Prevous issues, like language, use of unleavened bread, etc. have been mooted somewhat). Then the whole Vatican II Novus Ordo and its abuse.
At point efforts would be better rewarded in coordinating common action from what is common in faith, e.g. against abortion, redefinition/devaluation of marriage, charities etc. and see if or when that leads to Church structure.
Some of your points are well taken, but a few seem off. For example, there are exceptions to allowing married men as priests in the RCC, even though celibacy is the rule, and of course, generally, priests are not allowed to marry after ordination. Also, Greek Catholic or Eastern Catholic, or Byzantine Catholic infants are chrismated by the priest at the time of the baptism, when the infant also receives the Holy Mysteries, so perhaps you are speaking of the Latin or Roman Church where chrismation, or confimation, is given to young teens. But the Greek Catholic priests are in communion with the Vatican.
BTW, I am not sure what name you are associating to the Greek Catholics, or Byzantine Catholics, since you have insisted on using the name Catholic for the Orthodox Church only.
