Yes, sorry - I should have posted something earlier. Yours looks really good.
I have made some progress, albeit not as rapidly as you have. I have decided to keep and use the rear Aero bumper which I obtained. I have managed to get the finisher (with curved ends) for the bottom of the tailgate from a BMW dealer in the UK who was reducing stock ( about £40! - c$60, in primer) and the correct bumper reinforcement panel needed for this instal ( same sort of price for a new one from an eBayer in Germany) - as you say, you don't need that for the M-Sport instal. All I need to do now is to get the bumper and tailgate finisher painted in Mystic Blue. I have been a little slow in sorting that, but I will do something about it soon.
I will post an update when I have done that - keep hassling me if you don't see anything from me during the next few weeks! Regards, Alan
