I don't get the question. Anything less than a legally recognized union would just be a symbolic jesture with no legal (or spiritial depending on the ceremony type) weight behind it.

Ah never mind. I think you were referring to a church ritual. Although that would be ideal as you wouldn't have people running around condemning other people as abonimations before God, I think legally recognized civil unions would be more practical (not to mention realistic) than trying to change some factions of christianity of their belief systems.

Civil unions would also adress some of the more day to day practical aspects of why gays want to be recognized as "married" such as insurance and medical descisions and benefits.
