That sounds like a formula for creating a seatpost that will quietly go into a two piece mode mid-ride. Ie, your seat and clamp assembly will neatly fall to the road. The stresses created doing the bend will be significant. Aluminum really doesn't like seeing big stresses, then many repeated stress cycles later. Breaking while in use with no apparent warning is what aluminum does.

I did bend an aluminum seatpost many years ago. Hit a frost heave I didn't see at over 50 mph. Seat kicked me and the bike into the air hard. Post bent back a few degrees. (In a race, going down Smuggler's Notch in VT in light rain. I couldn't see through my glasses.) Two weeks later I was on a replacement post. That I won that race! But they gave me the wrong diameter.
