Anything is possible, if you're willing to spend the cash. I'd ballpark a swap like that at between $15,000 and $20,000. You're talking about custom engine mounts to get it in, the price of the engine itself, and a lot of wiring harness and DME work as the E39 is about a generation behind the cars using the N54. You'd probably be able to use E39 parts-bin upgrades for the suspension and brakes to handle the extra power, and the stock trans might be okay since the 540i was putting down similar numbers.

At the end of all that, you'd have an old BMW with $20k in parts and mods, worth about $10k. On the plus side, some mechanic's kid wouldn't have to worry about college.
