The Zouave could easily be turned in a 5e fighter subclass.For the people talking about ways to make a warrior interesting without more spells. This is a topic that has been explored by the GLOG. I give you
The zouave: a veteran coming back to the world of adventure. they have to knock off the rust, but their experiences give them special knacks
The gun priest: their faith and their gunslinging give them abilities.
Of course you would have to re-stat that in 5e but... making balanced stats is not that hard. Good ideas? That's hard. The GLOG design ethos is one of constant rebuilding and hacking, so the authors won't mind if you "borrow" their ideas!
Low-level spells being able to create effects like that though are pretty classic in D&D.I still don't like the genie warlock. I want to like it, the basic concept is definitely something I'd like to use, but the whole portable minihouse in the vessel as a low level basic ability just is way too goofy for my tastes.
