Koen, what do you think about a paraglider style air intake for one or two impeller propulsion exhausts ?
If you know a bit about ducted fans, you will understand why this is a bad idea. The intake of a ducted fan needs to be large in area than the area of the prop. This book by Marc De Piolenc is a must read if interested in ducted fans. It helps to prevent the common mistakes in design.

Doesn't that completely negate the "cheap and simple option" which the OP was looking for?
Indeed, but that ship sailed with the mention of in-wing propulsion.
Simple would be going with a half dozen little electric props and motors sticking out of the leading edge.
Using six means you can use the larger-scale RC props and motors.

Isn't sharknose just a new name for leading edge cuff or STOL cuff? Perhaps sharknose is easier to advertise and promote than leading edge cuff or STOL cuff? This profile has had all manner of application over the past century several were designed for the Cessna wing for example. A friend had a Robertson stall kit on his 180 but used a Sportsman cuff instead of the Robertson, not strictly kosher but it worked well.

Holy thread drift Batman!
The Sportsman STOL conversion is especially popular with skydiving operations because it increases wing area by extending the leading edge 4 inches forward, The flap gap cover also improves climb performance. Finally, a single-engined Cessna with a Sportsman STOL kit still fits into a regular T-hangar.
OTOH you need to add the Wing X extensions to legally fly a Cessna 180 or 812 with 4 jumpers because the Wing X kit allows an increase in gross weight.

You need to know that Panamarenko is a artist who makes just strange (technical) items. None of his creations ever flew.

But it was very weird to me to see that when NASA was experimenting with multi props on wings that this artist thought about it when he was young. He recently died of old age. The design must have been 40-50 years old.
