I'm rather certain that will be different on other bikes.
I am of the opinion that the crank area is one of high turbulence either way and therefore does not work in the same manner as a TT wheel.
Then, I thought the "myth" of more spokes more drag had been debunked or at least questioned as of lately. The spiderweb is much tighter, so the "spokes" would draft of each other, too.
I'm sure you can optimize crankarms and rings to save some time, but honestly, I would just get the chainrings I like, maybe because they look cool, maybe because they shift well and not let get aero concerns in my way.
