I'm with Moss on this. Excavation is destructive and these days, under Valletta, its only done if the archaeology is threatened. I realise there's a case for "restoration" of Avebury but in this case, unlike some, restoration can't be divorced from excavation so we have to tread very carefully.

"I define 'responsible' in this context as the restoration of our heritage in the shortest possible time".
Pourquoi? Where's the threat? What's the hurry?

(I feel very mean to myself about this as I'd love to see the full set up, and it would probably give more pleasure to more people than saving the knowledge for a few future archaeos. But when it came to it, with the diggers poised, I think i'd wimp out of saying Go!)
