I used .034 aluminum - stiff enough to hold shape, but easy enough to work with, and yes I thought about the same thing since I think it would help if fan shroud was angled to the fan opening size. Give a smoother flow for at speed running, but I think you would need more length than I had to work with to get an angle that would do any good. If you look at my pics after I was done there was only about 1.5 inches between fan motor and water pump bolts. I am really thinking a 3000 CFM instead of my 2350 cfm fan tight up against the radiator like mine was that covers the radiator (my 16 inch only lacked 1/2 inch on either side to cover radiator) would do a good job without fan shroud idling and give much better flow at speed. I am ordering a new overflow tank right now and will try and drive it again this weekend. I really think the inlet shroud is a must, but am not sold on the fan shroud yet.

The angling would probably help a lot if you have room.
