At any given time, half of earth is shined upon and half is in darkness. Those two hemispheres have rotational periods of 24 hrs. The whole planet gets 12 hrs. light and 12 hrs. darkness.....per rotation.
Now double the spin rate. Now we get 2, six hr. periods of light and 2, six hr. periods of dark.....for the same total of 12 hr. light and 12 hr. dark every 24 hrs. Same amount of light per 24 hrs.
Any difference the tilt makes.....is countered by that same tilt....six months later. For a light duty cycle of 50%. Any spin velocity gives 50%. Even very slow ones.
The only way to increase the amount of light is........brighten the sun.....or move closer to it.
Even if one could squash the "elliptic orbit"......to bring us a closer perihelion........it would also move the aphelion further away.
