Imagine the additional credibility this position would gain, within the "public square" of the USofA, the world - if not among its own traditional remnant - if Pope Francis were to state publicaly that the exclusion of women from the fullness of sacrament was an intrinsic contradiction to its comittment to an ecumenism of inclusion - in the church and in the world. 
He might even be able to add that while the "ecumanism of conflict" needs to be addressed, the fruitful inclusion of women in the ministries of evangelical protestantism offers us learning.
It would certainly distance us from the Trump leadership of exclusion and diminution, if not also the denigration, the abuse of women- a loophole the Trumpists will likely exploit, rather "bigly".
