Did you want button or zip?
There is a jacket in bulky with a shawl collar, but I don't think that would be too hard to convert to a hood, would it? (#249)
One using Q&T, size 4 is the smallest it looks like.
This one is worsted, but maybe you could hold two strands together.
Looks like the recommended yarn for this is more of a ribbon type one.
Again not hooded, but wouldn't be hard to add one I think.
