Are the "strakes" you propose like the ones on aircraft like the F-16 and FA-18? Would they be tilted downward for down force?
Strake (aviation) - Wikipedia, the free encyclopedia
The strakes on the aircraft mentioned above are what the Wikipedia article calls "Leading edge root extensions (LERX)" Their function are "provides the same additional vortex lift at high AoA by leading edge suction" Unfortunately, the very low aspect ratio makes them very high drag compared to a high aspect ratio canards.
Even canards with a strong anhedral (inverted V) would not work in a severe bank as the windward canard would at that point add a lateral lift in the wrong direction. The leeward side would add a down force vector more normal to the road surface which is what we want.
Too bad there isn't a simple wing solution for motorcycles like 4 wheel race cars can use.

... To complement the storm strip, a cross section where the top curvature is flatter than at the bottom could reduce lift.

I'm not sure I follow. Are you suggesting an inverted wing-like profile in the elevation (looking horizontal from the side) view?

Lots of work to do on stall aerodynamics and the effect of the Kamm tail on cross winds .

Amen!
