Steepening the head tube angle will quicken the steering. I'm not sure you'd want that when you plan to carry significant weight on the fork mounted rack.

That 440mm A-C measurement probably shrinks to 400mm with the rider on the bike as 50% static compression is typical. So a rigid fork with a 400mm A-C should be correct.
