As with Puma Punku, I agree with you that something happened to cause the PW stone to be found lying on top of previously u/k megablocks.
It's not a fair question to ask/demand of you to date when this happened. Noone before you has been able to - or at least I'm in the camp which doesn't believe the Romans did this. They could have but not the largest blocks in Baalbeck temple in my view.
I used to go into greater detail in years past and looked forward to the discussion - much like you do - but have accepted that peoples minds are made up...facts ignored ie: Serapeum - which noone can explain to any degree of satisfaction.
I don't agree with all you write but I for one enjoy the alternative exploration you bring to the table. You/we are outnumbered is all.
