I agree with Gargoyle, to many variables!!
and now I'm gonna add another one.....
Question, are you trying to just go with one winter quilt?? Or can you add something to make what you have already, work?? Something I've just started working with (I'm making my own and will start testing soon) is IX insulation. You might want to look into just adding a layer of that to what you already have.
