Heck yes. I'd love this. Personally I would like the option to officiate at Gribbo and Volo's wedding (Very Chaotic move) back at our camp. And they can stay there in marital bliss.
Until she eats him of course...no big loss.
And the trader makes sense as well, they should stay out of it. Zhents aren't known for sentimentality so I don't see why they would get involved.
