I'm not a fan, but I know how you feel about the Ros- names. I personally like Rosalie. Also, I thought I'd mention Rosfrith (I always want to say Rosfirth). I'm not sure what it means, unfortunately, but I've seen it used (Rosfrith Murray worked with her father James Murray on the OED). For some reason I like it and think that it's nicely unique like Roswitha.
ETA: I think it might be "famous peace" (from Germanic elements hrod "fame" + frid "peace").
