I got to hand it to you Justin, you keep thinking of new ways to modify your bike! 18 inch apes seem pretty tall - that's got to put your hands higher than your shoulders . . . never riden one like that but it just looks uncomfortable when I see one on the road.
Where are you going to mount the pillion seat? On the rear frame extension or directly on the fender?
You're going with slam brackets and relocated shock studs? If I am following you correctly, that will lay your shock down at a very low angle. Should look pretty cool!
I know you will (!), but keep the pics coming . . .
