If you've changed the dome lights for LEDs and put LEDs in the footwell the current draw will still likely be well below the original filament bulbs, so I can't see it causing any issues to the BCM ;-)
The risk (and it's a real one) around the BCM isn't about the current draw, it's the potential for chunky repair bills if you short it. It's happened enough times. If other, less risky, sources available, use them if you haven't already started the job.
