I'm afraid not. Genesis 2:24 clearly states God's original intention for marriage as between one man and one woman. The fact that humans did as they pleased does not negate that. Jesus merely restated God's plan for marriage to the Pharisees who had so twisted the institution for their own selfish ends.

There's nothing like "equal" or "unequal" divorce in the Bible. Divorce is divorce, period - and God hates it. God, through Paul, affirms monogamous, heterosexual marriage in the following verses:

1 Timothy 3:2 A bishop then must be blameless, the husband of one wife, vigilant, sober, of good behaviour, given to hospitality, apt to teach;

1 Timothy 3:12 Let the deacons be the husbands of one wife, ruling their children and their own houses well.

Titus 1:5-7 For this cause left I thee in Crete, that thou shouldest set in order the things that are wanting, and ordain elders in every city, as I had appointed thee:
If any be blameless, the husband of one wife, having faithful children not accused of riot or unruly.

All these verses set out God's intention for marriage. No mention of polygamy or same sex marriage there.
