Would this favor Monastics for the bishopric positions?
Yes, but there would be many widower bishops. About 10 percent of Orthodox bishops are widowers, are rarely, ecclesiastical divorces (i.e. wife becomes a nun). Even until the 7th century there were Bishops with wives that if my memory serves me right, even lived with them (canons required taking care of one's wife). And so, theoretically this canon can be reversed simply because it is disciplinary. However, theoretically bishops who cohabitated with their wives were not supposed to be sleeping with them.
Apostolic Canon 6:
Let not a
bishop,
presbyter, or
deacon,
put away his wife under pretence of religion; but if he put her away, let him be
excommunicated; and if he persists, let him be
deposed.
Canon 12 of Trullo:
Moreover this also has come to our
knowledge, that in Africa and Libya and in other places the most God-beloved
bishops in those parts do not refuse to live with their wives, even after consecration, thereby giving scandal and offense to the people. Since, therefore, it is our particular care that all things tend to the good of the flock placed in our hands and committed to us — it has seemed
good that henceforth nothing of the kind shall in any way occur. And we say this, not to abolish and overthrow what things were established of old by Apostolic authority, but as caring for the health of the people and their advance to better things, and lest the
ecclesiastical state should suffer any reproach.
Canon 48 of Trullo:
The wife of him who is advanced to the Episcopal dignity, shall be separated from her husband by their mutual consent, and after his ordination and consecration to the
episcopate she shall enter a
monastery situated at a distance from the abode of the
bishop, and there let her enjoy the
bishop's provision. And if she is deemed worthy she may be advanced to the dignity of a
deaconess.
