There's nothing really new under the sun. All these items you mention above have been studied for years. Tip vortex reduction is why many aircraft use those tip fins on the wings. It's also why sailplanes use the Schumann planform in a lot of cases. For the ultimate use of the ground effect google for ekranoplane. The rest of the stuff is all things we modellers use or not as needed depending on the flight mission of the model. As for the "air pockets" look up "separation bubbles" and "laminar flow" as it applies to airfoils. Then go look for information on turbulators, invigorators and other options for forcing the earlier breakdown of the laminar flow and why this is often preferrable to extending laminar flow even though there's a drag penalty. All this and more is out there either in books or on the web. I'm not trying to shoot down your enthusiasm but it's wise to study the field of existing aerodynamics and then see if there's a hole in there someplace. Since most study has been aimed at full sized aircraft that operate at far, far higher reynolds numbers than our models there's actually a LOT of holes as pertains to our size of airplane building. Most are not really important as any drag penalties are actually an advantage as in the flat foam 3D models that use the "bad" charactaristics to advantage and in a typical sport model just adding a bigger engine will mask a host of drag issues. Also it's not like any of our models flies in a steady state for long. If they did they'd soon go out of sight. So in real use our models are constantly shifting radically through a very wide range of lift coefficients so even trying to select an airfoil that is optimized for any one small range of use is a useless passtime in many cases. Having said this there are a few specialty areas in modelling where all my downplaying of this is not valid. These are such things as racers, sailplanes and heavy load lifting designs as used in the SAE contest.

So best of luck with picking your topic. I also suggest that you'll likely get better marks if you really narrow down on a topic and then dig deep rather than a broader field with less in depth analysis. At least all my prof's liked the more focused and deeper study.
