Even if I drill it out it's unclear whether I'd be able to remove the intake manifold because of the one that broke, and if I am able to remove the intake whether I would have any of the broken bolt to grab on to.
Anyone ever removed the intake manifold on a Mercedes with a 5.6L engine and might happen to know offhand?

Keep trying on that stubborn bolt with PB or Kroil, and working it back and fourth. If it breaks, you may still be able to remove the intake with them broken because IIRC, they're nearly vertical, and the intake comes straight up, and off.
If there's not enough left to grab onto, you'll just have to cut it flush, and drill, which is no fun on a steel bolt in an aluminum head. It's hard to keep the bit centered.
If it comes to that, of course, start with the smallest bit you can safely use to make a pilot hole first, then the next larger bit in your index, then the next, etc... Good luck, man. :(
