Its going to cost an absolute fortune to do anything with that. £345,000 already spent just getting out. Whilst I agree with the comments about enemy aircraft, I would rather see the money spent on getting 'Just Jane' airborne in Lincolnshire at the heritage museum. The RAF Lanc is not going to last forever, nor is the Canadian one, and the powers that be don't seem to be interested in keeping the iconic Vulcan airworthy.
I put this in the same category as trying to get the 'Mary Rose' seaworthy 
The biggest problem with the Vulcan is the engines.
Unless Rolls Royce find a way to refurbish those engines then the CAA will ground it regardless
Yes, they are looking at finding away too sort out the impeading airframe problems but without engines, the flying program it totally buggered 
Or wishful thinking I know, bribe / blackmail the CAA and get one of the Lightning's back into the air

Apart from what has been said above, all these projects rely on cash sources of different types, but mainly from the public. The government has no money, so the likes of the RAF are too busy keeping their front line aircraft in the skies to part with money for more "history projects". The Battle of Britain flight is enough for them, let alone keeping the Red Arrows in the air.
No, all these projects being discussed are basically being funded from people like you and me with their own objectives. Those that want to get the Lancaster in the air are different than those who want to fund the saving of the last Dornier 17. The Vulcan fund is something else. Some kind benefactors contribute to many of these projects, whilst others will fund just one "pet project" as we do with steam railway engines.
At the end of the day though it is up to the donors what they contribute to, and whether you favour saving the Dornier or not makes no difference; it is what they want that counts and means something is achieved or not

It is also true that the crucial factor now is the technology involved and keeping old engines / air frames in full working, insurable, order - as it is with steam engines- has become increasing expensive, problematic, and one day impossible due to costs, age and many other factors.
