I'd say the spring rate will be the culprit, as 545/550 will be heavier as oppose to 525/530 as other common after market brand like Eibach and/or H&R usually grouped/paired part number for 525/530 model and 545/550 model but have not notice a single generic part number for all E60 model.

As BlaSTiWi said, the rate of the springs will be different, as the V8 is quite a bid heavier, especially at the front.

Unless you want to play "Kangaroo Jack" on bumpier roads, I wouldn't do it.
