It wouldn't make mainstream "conservatives" happy, but that is simply because they are so utterly ignorant to how legally different marriage is today compared to a few decades or worse don't mind it at all, not minding the incongruity. It would make traditionalists happy. They could recreate much of what they miss about modern marriage.
Take for example penalizing the partner who is cheating in divorce settlements, this is something I know no Slovenian court will ever take into consideration but something people who actually want a traditional marriage would love. In general maybe some people would like to make divorces more difficult because they in general don't approve of them. Maybe some people think default custody should de facto lie with the husband instead of the wife (as it does currently). ect. ect.
Before you think there aren't any people who look at it this way, note that I've seen enthusiasm for this concept on very hardcore Christian right wing blogs like the Orthosphere and The Thinking Housewife.

Careful, you need to weaken the political power of feminism first, otherwise they will try to pass restrictions on the types of marriage contracts to be enforced, similar to the restrictions on employment contracts.
A thought occurred to me today as I skimmed an article in a rationality forum where the subject of gay marriage cropped up; seeing as the issue has been hotly contested in various public fora and especially the courts, what about poly? After all, many if not all the arguments for gay marriage apply to poly marriage as well.
Questions for LWers who are currently in a such a relationship, or have an opinion to share:
Do polies want to marry each other or do such relationships not lend themselves to permanence above a threshold of partners? Should polies campaign for the right for a civil union anyway? what are the up and down sides of this? etc
