Maybe you could pull the oil pressure sensor, or watch the cam shafts for oil weeping per mkov's video, while bumping with the starter? I know, you've turned it a lot unlubricated and are walking a fine line here.

It's not THAT hard to pull the pan again, pull the rod and journal caps one by one, the cam caps, and put the pink engine assembly lube on all journals and tighten back up. Guess you'd need new bolts and what not. Just brainstorming.

I poured the oil over the valves and primed the engine with cool packs unplugged... I forgot to unplug the fuel pump relay. I realized this on the third 10 second priming sequence. I knew I already had oil mixing with gas... So I connected the coil pack plugs and tried to start her up. Ittook three tries because it was sputtering out the first two times. On the third time it was sputtering and I gas her some gas and... Vroom. She's running like a Swiss (well, German) watch. She's idling quiter, and the death rattle is gone. I'm not hearing any mini rattle from the slack on the oil pump chain either. I cleared the errors and the adaptations and I think it's good to go. I took her on a short drive and it drivng smooth. Going to stretch her legs later today.

Thank you all for you advice and support. I learned a ton about my car, and I have a lot more confidence in my ability to turn a wrench. I also really really appreciate this community. I hope I can pass it in to other R56 owners soon.

I was planning to pour oil all over the area under/around the cams and specifically in the 8 little drain ports 4 on the intake side and 4 on the exhaust side. Then I was going to pull the fuel pump relay and run the starter 4 x 10 seconds like I saw on a YouTube from some BMW technician. I was going to start the engine after that. I’m pretty sure that all the other components/sensors were fine, it’s just that I goofed and didn’t have the chain on the sprocket behind that cover. I hand cranked the engine many times yesterday and confirmed that the oil pump sprocket is spinning.

IM me & I'll email you the mini procedure.
