Hey there Zedicus,
Very cool tail light integration. Just about anything that cleans up the rear end of the bike is worth doing.
The easiest forks to swap are the first generation CBR600 Hurricane, or the early Intercepter forks. The are the same diameter fork tubing & spacing to slide up into the Ascot triple clamps. The Hurricane uses a 17" front wheel, plus the rear 17" wheel will slip right into the Ascot swing arm. The Interceptor front end uses a 16" front wheel. Both of these front ends will lower the bike in the 2-3 inch range.
Neither of the Ascots are well suited for clip-on type of bars, as it will really pitch you forward with the stock seat height. The bikes are supposed to have a more relaxed dirt-bike type of feel to them. I like the Honda CR type of bars. They come in 3 heights, low rise, medium rise & high rise. The low & mid rise bars are real nice. I've seen an FT Ascot with drag bars & one with clubman style bars. It really looked dumb, uncomfortable & mis-matched. You have to be careful with those types of bars, that your hand controls don't dent the tank at full turn.
I used this headlight, mounting ears & turn signals set-up, but I requested black bodied turn signals:
