Hey its just nice to be of help. I was worried for a while that I was just pinching all your top ideas and not giving any back.
Your ideas are great as always.
Few minor points:
With regards to SIS, they moved into their present accommodation at Vauxhall Cross in 1994. Glad you increased the size, at the height of the cold war MI6 had more agents working the other side of the iron curtain than the CIA.
Mebyon Kernow, the newest draft has downgraded the size of the leadership. You originally had it being lead by I believe an ex Royal Marine? Reason for the change?
Got my current draft of the complete British Army ORBAT almost done for you to take a look at, if you have the time could I email a copy soon for your perusal?
