Not strictly what the OP wants, but for anyone else reading this thinking along those lines.... As a living history person, doing late 18thC/early 19thC, I've made a few cloaks now and all have hoods. Nice schematic in this book:

Which could easily be adapted to a shorter, different shaped, cloaky thing body... My son and I spent a while winter wearing our 18thC cloaks in the house rather than light the fire in the daytime - warm as toast if made from decent broadcloth (although at £100 a metre you have to get lucky with a mill shop...)
I had an old friend who'd think nothing of walking round the local city in her 18thC cloak. No-one batted an eye-lid. But it always made me smile, spotting her in town.
As a living histry person, it strikes me there are many useful items from the past that you could adapt.
I am about to add a hood to a coat I made but never wore cos I hate the lapels. I realised I could pull the lapels right off, and replace with a hood so turning a nice cashmere/wool coat I've never worn into a staple. (Luckily I had enough of the fabric leftover). As it came with no hood, I am using the hood from another coat pattern I have, that I know will fit. I often swap things like hoods and pockets round from different patterns I already have if I prefer the one on an old thing I know fits me, or that has better pockets, or whatever.
