I simply would absolutely not want more than 6 gears...

Do you find yourself cruising down the highway thinking that you wish the engine were running at a lower RPM? That is the only thing you'd gain by adding the transmission from the GX. So, assuming you didn't change the final drive gearing, you'd be rolling around at 1500rpm or similar at 70mph.
Actually? Yes! That's exactly what I want. With cruise control on at 1500rpm I can get 23-24mpg *easy*, as opposed to the 19-20 I get at 2000rpm....
In fact~ I decided to do the math...and please correct me if my math is wrong... it's late and I'm tired! LOL
Assuming gas is at $4/ gallon, over the course of 100,000 miles at 20 mpg you'd use 5000 gallons and spend $20,000 on gas: but before you freak out... at 24mpg you'd still use 4167 gallons and spend $16,667 on gas. That's only $3333 dollars, which over 5 years isn't that much, though I'd rather put $55 worth of sushi in my mouth each month instead if feeding it to Mobil etc~
And that's just at $4/ gallon
Now if the 5th gens are as bullet-proof as past models my intent has always been to use mine as a daily driver until it's paid off (at around 100,000 miles) and have it as my second/ fun/ beach/ foul weather/ ski trip/ utility vehicle forever after. That long-term plan was one of the primary reasons I chose a 4Runner over anything else in the first place!
HOWEVER: if Toyota added a 6th gear like you described as a mid-model upgrade/ refresh I'd trade mine in tomorrow and without a second thought. By the time it reaches 200,000 miles at Lord-knows-what-price I know I'll be way ahead of the game, as gas won't be getting any cheaper over time...
Stanley - Agreed. Wind resistance plays a HUGE role in fuel economy when you're talking about highway speeds. Aero drag is a function of the square of velocity. More than likely, at 70mph, the 1GR doesn't make enough power at 1500rpm to maintain that speed. Thus, the transmission would downshift to 5th gear anyway. Unless the engine and gearing combination makes enough power to overcome drivetrain, aero, and rolling resistance drag at 70mph and the engine spinning at 1500rpm, that extra 6th gear is a complete waste.
Personally, I'd rather see them do a hybrid with an electric motor powering the front wheels. You ditch mass of the transfer case (that is parasitic drag savings via removing inertia) and you get the ability to recover energy that is normally lost to braking. The Lexus LS600h uses an eCVT (soooo much more simple than a traditional transmission and a bigger range in gear ratios so the engine only spins as fast as it has to) with a 2 speed reduction gear on the electric motor, which sounds as if it could be used as a low range. That is something I'd trade for my 4Runner.
