The idea that Stonehenge, or a Stonehenge-type structure, once occupied the top of Silbury is not as wild as it might seem - there are examples from other parts of the world of temples, even whole cities, being dismantled and then reassembled elsewhere, or old structures being deserted and new, similar structures being built elsewhere.
I would go more for the mound being erected in memory of the circle of stone that once stood beneath it. I doubt the structure of the chalk blocks at the top of the mound would take the weight. That saying, there is still the lingering bluestone mis-history to consider...
