Another kind of silly idea would be to try and find a wrecked 4.6is with an intact motor. Or, just buy another cheap 4.6is for $10k and take the motor... Sell the rest of the parts to guys like us.
I just really question the likelihood of finding a used 4.6 motor. There may be new B46 crate motors in a BMW warehouse somewhere, that would be a real treat to have.
Hopefully you can use this as an opportunity to rebuild the truck stronger than before. Still a hard pill to swallow.

Haven't found a single one! And I don't have time to swap this motor right now. I'm already in the middle of a Duramax swap on my other vehicle, as well as painting my truck and rebuilding the rear end on my Scout. Too many projects torn apart!
I've been looking over manuals for the M62, and learned a lot about the Vanos and associated parts. But I haven't been able to find information on the oil path. If the oil is fed from the pump, then through the filter BEFORE the Vanos then I'd actually have some confidence that the rest of the motor has been protected. The only areas that would need flushing would be the timing chain case, and the oil pan. Then it's just a matter of replacing the oil pump, timing chain, guides, and gears. All of which I'm still going to have to farm out to somebody else.
I contacted VAC motorsports today because they rebuild Vanos units. They don't list the M62 as being part of their program, but I figured it wouldn't hurt to speak to them about my situation.
