I'm not sure you'd want to push the 40D to ISO-3200 without some kind of noise reduction. Even at ISO-3200, I don't think the 40D files are going to be as clean.
Also, consider, that at f/2.8, you are still two stops slower than f/1.4, so, you're still going to likely be shooting 30 second exposures, unless you're under some really dark skies.
Just a hunch, but, still worth a shot, because once you've reduced the RAWs down to video resolution, you may still be able to produce decent timelapses. I guess the other thing to remember is that you can always push the RAWs a stop in brightness in DPP. Might still be worth it.

All perfectly valid points.
I've
done timelapses before with my 40D and Sigma 17-70 f/2.8 so if I have to do 25-30s I know I can, and yes, I usually increase the brightness in post-prod.
I tried ISO3200 once and it was way too noisy on the 40D.
I just want something with a wider field of view.
