Yes but consider the price of a brand new inlet manifold to replace the swirl flaps.
Although BMW did manage to increase efficiency and reduce emissions by introducing swirl flaps, they only managed to do so by introducing a risky point of failure. It seems negative to remove something doing good, but if the cost of doing good is the large potential of major engine failure, I'd suggest foregoing that.

Not sure that the swirl flaps make that much difference at that mileage. The flaps only work and tick over and a little above, when they get clogged up, google photos, are they doing their job anymore?
If you want to keep them, maybe regular dismantling and cleaning would help.

Swirl flaps. I know most people simply remove them and put a blanking plate in, but is there any way of replacing them so they function but they're not a threat to the engine?
Car has done 75k, I was thinking - instead of removing the swirl flaps, could I replace the manifold instead? Is that a stupid solution. I don't mind paying more for the part as removing the flaps increases emissions and decreases engine efficiency.
