I wud think it is harder than it appears. you could get a fg shifter mechanism from a wrecker and experiment. if I was gonna look at doing something like this, I would prol go down the route of cutting both shifter stalks in half, and having them joined. then tinkering with the selctor rod to disengage gear locks. I dont think the shifter surround would work unless you grafted that part of the console into a ba one. that would mean fibreglass, bog, paint. dont start it unless you have the skills/ patience to finish.
