So… perhaps a spur-- my thoughts about this whole thing were around fin tips and “thrusters” pumping.
Cool stuff Janklow. Made me think of the picture below:

Interestingly enough, googled "Jeff Ho Flexfin" and was directed to a Sway's thread with the very picture I had in mind!
You've been poring over the F1 technical regulations looking for loopholes regarding moveable aerodynamic devices again, I see.
Leading edge root extensions
Although not as common, another high-lift device is the leading edge root extension (LERX) or leading edge extension (LEX). A LERX typically consist of a small triangular fillet between the wing leading edge root and fuselage. In normal flight the LERX generates little lift. At higher angles of attack, however, it generates a vortex that is positioned to lie on the upper surface of the main wing. The swirling action of the vortex increases the speed of airflow over the wing, so reducing the pressure and providing greater lift. LERX systems are notable for the potentially large angles in which they are effective, and are commonly found on modern fighter aircraft.
