Wanted Minifee Single Jointed Knee to Double Joint Mod

I love almost everything about my minifee's posing when she's strung right. except. she. cant. sit. on. her. knees. I've thought about just replacing the body, but I like that there is a large market of clothes made for the body, and, and it's very unlikely I'll find a resin match for the head as good as the same brand just a few years apart. If it's something you think you could do please DM me so we can talk price!
