Since the game release in 2011, I've never married anyone. Thing is I've always wanted to marry either http://elderscrolls.wikia.com/wiki/Lisette/http://elderscrolls.wikia.com/wiki/Vivienne_Onis, but they are not available. I just recently found out that I can use http://elderscrolls.wikia.com/wiki/Talk:Vivienne_Onis on them to marry. So I have some questions here.

After using console command, can I just wear http://elderscrolls.wikia.com/wiki/Amulet_of_Mara and approach them normally as I would with other marriage candidates and go through everything normally?

And for anyone who married these 2 before, will there be any bugs afterwards?

I married Sapphire by console, so it worked fine.

Doing the console commands is a bit hit and miss. Doesn't work on some Skaal villagers, I heard. It's best if you make a hard separate save and then do it. If you experience bugs, you can always go back
