Why?
I would say that it wouldn't be such a good idea, firstly because cylumes aren't exactly the best emitters of light. There would also be a great amount of attention given to the sight picture approach of this dim 'T' perhaps to the detriment of the awareness of the speed/height combination. Even in normal daytime approaches, it takes a lot of balls for someone to call, 'going round', solo or not. I think you're opening a huge can of worms here.
Great in a tactical environment , but why in any other ... cost, getting round planning permissions ?
The thing about NATO 'T's is that they are very good, but if you are expecting the lights to be 10m apart and someone has set them out at 5 or 20, then the final part of the approach will be 'emotional'.
Given the right training and kit, it's perfectly safe to simply throw a single activated IR cylume out the window and make an approach to it on goggles, but only really advisable in big sandy/clear areas
Perhaps the only 'NATO T' you should be thinking about is the 'White, 2 Sugars' one
