I, too, would like more "bolster" support. My Land Rover LR4 HSE LUX had adjustable side bolsters in the seat back and more bolstering on the seat proper. That said, I also prefer as high a seating position as I can get for both off roading and interstate driving. This "command seating position" is one of the big reasons I have an LC. The other things I like is that the steering wheel can be tilted enough so that even in that high position I can still see all of the instrument panel - which was not the case with the LR4.
As for your height vs fit, I am only 5'8, but my inseam is less than 29" so I have a longer torso. My point is that not everyone who is 6'-whatever will have the same challenge when it comes to their torso length.
As for seat back tilt, years of computer work have left me with issues in my shoulders from holding/supporting my arms in a forward position. Long road trips don't help. A more upright seat back helps alleviate that as my upper arms can hang more straight down. (I also bring the steering wheel out and keep my hands low on the wheel on long drives.
The only thing impeding my fit with the LC driver's seat is my trailer brake controller. I need to find a different place to put it.
