Duane, Ed brings to light the salient point. This project would not be the sole pervue of one man. I would suspect you will need many people involved and while you say the cost is not an issue, I don't believe the sale of a perfect North Hollywood .44 Automag would come near to covering what you contemplate.
In fact, I suspect this might be akin to building a new car from parts. It might ultimately cost more than a complete Luger Carbine would cost.
They type of craftsmanship required for a proper restoration of a Luger Carbine is very rare indeed. Parts might take years to locate. Certainly a reblue and metal restoration might take years. I have talked to folks who say Ted has had their pistol for going on two years.
The wooden forend and stock will have to be addressed by someone else.
The only man I know of who could possibly do most of a project like this is John Martz. I know even he has someone else do some of the wood.
I hope you are a patient man...Jerry Burney
