You could do the Sansa Mystery Mini that just came out! She's pretty cheap, about $12 on Ebay!
Edit: There's also the Funko Rock Candy Sansa. She's SOO pretty imo and only $11 on Amazon!
Sansa is the first character I've been this way about, as well. I bought the GOT Tarot deck specifically for the Sansa cards.
Sorry about the link, it's an old one I had. Amazon has the Rock Candy Sansa figures in stock:
