If you used the Hexblade as the template to maintain some of the combat ability I think this could work really well. At least for the more magical flavors of Ranger. I like it for the same reason I like the Warlock as a chassis for the Warlord.
Yup - and maybe have the patron some ancient forest spirit. One that demands blood sometimes. Take the outlander background for skills and voila!
