The idea is a static body VTOL design that can hover stable in the air, and also go at high speeds very efficiently with wings. Could modify dimensions as needed, but general idea, I'm unsure if there's a major design issue?

Indeed, you clearly know what you're talking about. A little ramp at the front of the wing would help, with a divet on the other side of the hole to smooth the air flowing down into the other side.
Now you've just made a shorter wing. With big turbulence pockets at the tips. You should look at the DARPA challenge, the VTOL drone that will have to do a long course and deliver things. It's on YouTube.
The DARPA challenge seems like it was just to see what could lift the most weight, which I'm not really interested in. I'm interested in the most efficient rapid VTOL UAV design that can pick up and drop off a payload the average size of a food delivery from Uber Eats.
Here's the v3 I realized four rotors is necessary for stability.
