I'm not exactly sure what kind of hood you're looking for, but hoods usually are not gender specific. This means you can broaden your search to look for hoods in general--whether they're originally intended for man, woman, boy, or girl is not important. Nor is it essential that the hood be part of a vest either--any hood on any kind of garment--as long as it's the right shape--should work for you.
Secondly, it seems to me that once you find a pattern you like, you can follow the instructions (posted by others here and on the other thread you linked to) for a basic hood until you get to the directions for the hood's point. Then you could switch over to the pattern.
There are lots and lots of garments with pointy hoods on Ravelry (free to join). Have you looked there for one that suits you?
