Again I am in agreement with your points about women being capable leaders. 

However, I challenge again the idea that we as humans just serve with our brains and our hearts. Completely false. The ultimate act of service from Christ Himself on the Cross is a TOTAL gift of Himself in and through His flesh. Mary's ultimate act of service in making her entire bodily existence available for the Incarnation is only possible through her uniqueness as a female. Her ultimate fidelity shown by standing at the foot of the Cross is a precisely maternal/feminine act as acknowledged by Christ's recognition of her as mother to John. 

In a nutshell, women are of course capable of fulfilling the roles of those in Holy Orders. It goes deeper than that though in acknowledging the specific roles of men and women as male and female in salvation history. 

Finally, how exactly do you know God has other plans in view? What makes you sure of it based on Divine Revelation?
