I say go for it. My new '65 that I acquired in April 2015 doesn't have the trim, but I have the trim pieces from my old '65 camper special that came with factory air, and I also have some auxillary springs and a rear sway bar from the parts truck that I am going to swap in, as well as the air conditioning parts from the old camper special. And since I am doing so many things to upgrade the new truck with parts from other trucks and parts bought from suppliers, I am going to be adding the custom trim to my cab, because in essence, it is a custom truck. You Can Do It!!!
