Now, this might be the most obvious thing in the world, but couldn't the TFC simply set up a separate operation here in the US, register their aircraft here, and keep them in England under that sort of arrangement? Obviously there'd be significant costs involved in getting the A/C here to be inspected by the FAA and receive their US airworthiness certificates, but it would have to be less of a headache than dealing with the hidebound UK aviation authority.
Is that even feasible, or am I simply talking out of my hat?

I don't think the aircraft would have to be brought to the US to be inspected, I believe they can be inspected anywhere in the world by an FAA approved civilian DAR Designated Airworthiness Rep who can issue an AW certificate. Anyone know for sure?

With new build parts they have to be built to the exactly same specs as per original or if not the original material you go better in strength in todays standards.If the original drawings don,t exist or specs you can use an original part and reverse engineer.If that doesn,t exist you must go back to basics....
Use an engineer,draw it up,test it,modify it then test it again.With todays software like Solidworks,ProEngineer and Catia parts can be designed by engineers and within the digital world dynamic and static loads can be applied.They can go into assemblies and tested digitally by said engineers before a ruler is set on the sheetmetal.
I wonder what Mr Mitchell or Mr Messerschmitt would say,or the guys at Boeing or Airbus.

As an A & P I can order up a piece of Alum of the same type and hardness as the original and make a new skin. I can rivet it on with the same type of fasteners or the modern day equivalents, I then make the logbook entries. This is what I would do in simple terms if I needed to replace a piece of skin on our Spitfire. I can Read the book and do the work.
The TFC has to write ops specs for how this same repair would be done and get them approved by the CAA. They will have to list the exact fasteners type size, type and mfg. They will have to spec the Alum alloy the same way. This would be submitted to the CAA which would argue over things and require you to make changes. You then submit the revisions and further argue over changes. Finally the ops spec for that skin replacement gets approved some months after originally submitted. Now you can actually do the work.
They seem to treat the Permit to Fly A/c no different than if a factory was building an Airliner and then the Airline was maintaining it.
