I am thinking of cable shifting it and putting my shifters in a more convenient place though I haven't worked out just where yet. Maybe on the left hand side of the drivers seat.
Can do this without transfer case mods too. Shift into 4lo but don't lock the hubs and you'll be in 2lo. Done this a lot spotting campers and launching boats.
If you want to twin stick it, go for it but for the reasons you've named I'd skip it. An extra shifter in the floor is just in the way in a van you'll be in for months or a small rig like a jeep. I had an M38A1 with t90, OE twin-sticked Spicer 18, and a warn OD. that's 4 shifters plus a floor mounted parking brake between the seats. Neat conversation piece but it took forever to teach anyone to drive and had no room to get comfortable with that jungle-gym between the seats.
